The Harry Potter film series transformed a beloved book saga into a global phenomenon, launching many actors to stardom. From established British thespians to unknown child actors who grew up before our eyes, the wizarding world created varied paths to celebrity. Let’s explore how the Potter alumni stack up in terms of fame, considering their careers both during and after their time at Hogwarts.
1. Daniel Radcliffe: The Boy Who Lived On Screen
Cast at age 11 as the bespectacled wizard himself, Radcliffe became the face of a generation-defining franchise. His growth from wide-eyed child actor to respected performer happened under intense global scrutiny.
Post-Potter, he’s deliberately chosen eclectic roles in indie films, Broadway shows, and quirky TV series to establish himself beyond wizardry. From the horror film “The Woman in Black” to playing a flatulent corpse in “Swiss Army Man,” his choices show remarkable courage.
Despite his estimated $110 million fortune, Radcliffe maintains a down-to-earth reputation, often speaking candidly about the pressures of childhood fame and his past struggles with alcohol.
2. Emma Watson: From Hermione to Humanitarian
The brightest witch of her age transformed into one of Hollywood’s brightest stars. Watson’s portrayal of the intelligent, principled Hermione Granger resonated with millions, particularly young girls seeking strong female characters.
Her post-Potter career choices reflect careful consideration, balancing blockbusters like “Beauty and the Beast” with thoughtful indies such as “The Perks of Being a Wallflower.” Beyond acting, Watson graduated from Brown University and became a UN Women Goodwill Ambassador in 2014.
Her HeForShe campaign and passionate advocacy for gender equality have made her as renowned for activism as for acting, elevating her cultural influence beyond mere celebrity status.
3. Rupert Grint: The Wizarding World’s Loyal Friend
The freckle-faced redhead who brought Ron Weasley to life captured hearts with his comic timing and emotional depth. Grint’s portrayal of Harry’s loyal best friend earned him a special place in the Potter pantheon, with his expressive face perfectly conveying Ron’s fear of spiders and unwavering friendship.
After Hogwarts, Grint has maintained a lower profile than his co-stars. He’s appeared in indie films, stage productions, and television series like “Sick Note” and the psychological thriller “Servant.”
A notable ice cream van enthusiast in his youth, Grint has embraced fatherhood since 2020 and continues to charm fans with his authenticity and self-deprecating humor in interviews.
4. Alan Rickman: The Beloved Potions Master
Though already an acclaimed actor before donning Snape’s black robes, Rickman’s portrayal of the complex potions master became one of his most iconic roles. His silky voice and masterful ability to convey both menace and hidden depths made Severus Snape unforgettable.
Rickman’s career spanned Shakespeare to action films, with memorable roles in “Die Hard,” “Sense and Sensibility,” and “Love Actually.” His versatility allowed him to move effortlessly between villain and hero, always bringing gravitas to each performance.
His passing in 2016 at age 69 devastated fans worldwide, with tributes pouring in from Potter castmates who described his mentorship and kindness behind the scenes – much like Snape’s hidden goodness.
5. Maggie Smith: The Formidable Professor McGonagall
Already a legendary actress with two Oscars before Hogwarts, Dame Maggie brought gravitas and Scottish steel to Minerva McGonagall. Her impeccable timing delivered both stern reprimands and rare moments of warmth that made the Transfiguration professor beloved by generations.
Smith’s illustrious career spans seven decades, from Shakespeare to “The Prime of Miss Jean Brodie” to her scene-stealing role as Dowager Countess in “Downton Abbey.” Her razor-sharp wit and commanding presence have made her one of Britain’s most treasured performers.
Awarded a DBE (Dame Commander) in 1990, Smith continued working through cancer treatment during the Potter films, showing the same determination as her on-screen character. At 88, she remains an acting force.
6. Ralph Fiennes: The Dark Lord’s Terrifying Presence
Fiennes’ chilling portrayal of Lord Voldemort stands as one of cinema’s most memorable villains. His decision to play the character with whispering intensity rather than scenery-chewing bombast created a truly unsettling presence that haunted viewers’ nightmares.
An acclaimed Shakespearean actor before Potter, Fiennes earned Oscar nominations for “Schindler’s List” and “The English Patient.” His remarkable range allows him to shift between playing monsters like Voldemort and charming characters in “The Grand Budapest Hotel” or “The King’s Man.”
Fiennes also directed and starred in several films, including adaptations of Shakespeare’s “Coriolanus” and “The Invisible Woman.” His aristocratic bearing and intense commitment to his craft have cemented his status as one of Britain’s finest actors.
7. Helena Bonham Carter: Bellatrix’s Wild-Eyed Madness
Few casting choices felt more perfect than Bonham Carter as the deranged Death Eater Bellatrix Lestrange. Her manic energy, disheveled appearance, and gleeful cruelty made Bellatrix one of the franchise’s most memorable villains despite relatively limited screen time.
Long before terrorizing Hogwarts, Bonham Carter established herself in period dramas before becoming Tim Burton’s muse in films like “Sweeney Todd” and “Alice in Wonderland.” Her eccentricity extends to her personal style, making her a fashion icon for the gloriously unconventional.
A two-time Oscar nominee for “The Wings of the Dove” and “The King’s Speech,” she continues to choose diverse roles, from playing Princess Margaret in “The Crown” to appearing in blockbusters like the recent “Enola Holmes” films.
8. Gary Oldman: The Falsely Accused Godfather
Oldman’s performance as Sirius Black introduced Potter fans to one of cinema’s greatest chameleons. His ability to convey both the haunted rage of an Azkaban escapee and the warm affection of Harry’s godfather showcased his remarkable emotional range.
Known for physically transforming into characters like Sid Vicious, Dracula, and Winston Churchill (which finally won him an Oscar in 2018), Oldman’s versatility makes him nearly unrecognizable from role to role. His intense preparation and complete immersion in characters has influenced a generation of actors.
Despite limited screen time in just three Potter films, Oldman’s Sirius made such an impact that his character’s death remains one of the series’ most devastating moments, testament to the emotional connection he created with audiences.
9. Tom Felton: Draco’s Redemptive Journey
Platinum blonde and perpetually sneering, Felton made Draco Malfoy the bully we loved to hate. His portrayal evolved beautifully over the series, transitioning from simple antagonist to a complex character trapped by family expectations and fear.
Felton began acting at age 10 in commercials and small films before landing the role of Draco at 13. Post-Potter, he’s appeared in “Rise of the Planet of the Apes,” “The Flash” TV series, and independent films while developing a music career.
Ironically, the actor who played the Slytherin bully has become one of the most beloved Potter alumni among fans. His warm engagement with the fandom, regular convention appearances, and heartfelt appreciation for his Potter experience have earned him a special place in fans’ hearts.
10. Matthew Lewis: Neville’s Glow-Up Champion
Starting as the round-faced, awkward Neville Longbottom, Lewis underwent perhaps the most dramatic transformation of any Potter actor. His character’s evolution from bullied outcast to sword-wielding hero paralleled Lewis’s own physical transformation, which spawned the term “Neville Longbottoming” to describe unexpected glow-ups.
Lewis’s performance captured Neville’s heart and courage long before the character became physically heroic. His subtle portrayal of a boy finding his confidence resonated with anyone who ever felt like an outsider.
After Potter, Lewis starred in films like “Me Before You” and BBC dramas including “Happy Valley” and “All Creatures Great and Small.” His dramatic physical transformation generated massive media attention, though Lewis himself remains charmingly modest about his heartthrob status.
11. Evanna Lynch: Luna’s Ethereal Charm
Perhaps the most magical casting story belongs to Lynch, who was chosen from 15,000 girls after writing to producers as a Potter-obsessed fan. Her natural ethereal quality and genuine understanding of Luna Lovegood’s outsider perspective made her portrayal feel less like acting and more like embodiment.
Lynch brought Luna’s dreamy wisdom and unshakable authenticity to life with such precision that author J.K. Rowling herself said Lynch was exactly as she imagined the character. Her performance gave hope to eccentric kids everywhere that being different could be a strength.
Since Potter, Lynch has appeared in indie films, competed on “Dancing with the Stars,” written a memoir, and become an outspoken animal rights activist. Her continued connection with fans at conventions shows her genuine appreciation for the role that changed her life.
12. Robbie Coltrane: The Gentle Half-Giant
“Yer a wizard, Harry” – these iconic words from Hagrid, delivered with Coltrane’s perfect blend of warmth and wonder, launched audiences into the magical world. His portrayal of Rubeus Hagrid captured the character’s childlike enthusiasm, fierce loyalty, and tender heart despite his intimidating size.
Before becoming Hogwarts’ beloved gamekeeper, Coltrane was already famous in the UK for the crime drama “Cracker” and appearances in two James Bond films. His impressive 6’1″ frame was enhanced with prosthetics and camera angles to create Hagrid’s half-giant stature.
Coltrane’s passing in October 2022 at age 72 deeply affected the Potter community. In HBO’s 20th anniversary reunion special, he movingly reflected that Hagrid would live on through generations of viewers – a fitting legacy for an unforgettable performance.
13. Jason Isaacs: Lucius Malfoy’s Aristocratic Menace
With flowing platinum locks and a snake-headed cane, Isaacs transformed Lucius Malfoy into the perfect picture of aristocratic evil. His performance balanced chilling cruelty with hints of fear and desperation as Voldemort’s return diminished his status.
Isaacs famously auditioned for Gilderoy Lockhart before convincing producers he should play Lucius instead. This intuition proved correct – his sneering contempt and barely contained violence made him one of the series’ most effective villains.
Beyond Potter, Isaacs has played memorable villains in “The Patriot” and “Star Trek: Discovery” while showing versatility in films like “The Death of Stalin.” A vocal advocate for various charities, Isaacs often uses his platform to support causes that would make his Slytherin character shudder.
14. Michael Gambon: The Second Dumbledore
Stepping into Richard Harris’s robes after his passing was no small task, yet Gambon made Albus Dumbledore his own. His interpretation brought more energy and occasionally fierce intensity to the Hogwarts headmaster, particularly as the series darkened.
Already an established theatrical giant before Potter, Gambon’s illustrious career included membership in Laurence Olivier’s National Theatre Company and acclaimed performances across stage, television, and film. His distinctive voice and commanding presence served Dumbledore well through six films.
Though some fans debate the differences between Harris’s gentler portrayal and Gambon’s more dynamic approach (particularly regarding the infamous “HARRY DID YOU PUT YOUR NAME IN THE GOBLET OF FIRE?” moment), most appreciate how Gambon evolved the character as the stories grew more complex and dangerous.
15. Bonnie Wright: Ginny’s Quiet Strength
First appearing as Ron’s shy little sister, Wright grew alongside her character Ginny Weasley. Though the films significantly reduced Ginny’s role compared to the books, Wright brought quiet determination to Harry’s future wife.
Cast at just nine years old with no previous acting experience, Wright matured from a wide-eyed child actor to a composed young woman over the decade-long filming process. Many fans believe the screenplays didn’t do justice to Ginny’s book character, who was fiery and outspoken rather than reserved.
After Potter, Wright graduated from London’s University of the Arts with a film degree and moved behind the camera as a director and screenwriter. She’s also become an environmental activist, campaigning against single-use plastics and promoting sustainable living through social media.
16. Imelda Staunton: The Pink Terror of Hogwarts
“Hem-hem” – with that signature throat-clearing and saccharine smile, Staunton created one of cinema’s most detestable villains. Her Dolores Umbridge, draped in pink and wielding sadistic authority, proved more immediately hateable than even Voldemort for many viewers.
Staunton’s brilliance lay in playing Umbridge not as an obvious monster but as a prim bureaucrat who genuinely believed in her twisted version of order. The contrast between her girlish aesthetic and cruel actions made her psychological torture of students all the more disturbing.
A decorated stage and screen veteran before Potter, Staunton earned an Oscar nomination for “Vera Drake” and later portrayed Queen Elizabeth II in “The Crown.” Her range is remarkable – the same actress who made audiences shudder as Umbridge delighted children as the voice of Aunt Lucy in the “Paddington” films.
17. David Thewlis: Lupin’s Scholarly Sadness
Shabby clothes and premature gray hair couldn’t hide the dignity Thewlis brought to Remus Lupin. His portrayal of the werewolf professor balanced gentle wisdom with profound melancholy, creating one of the series’ most nuanced adult characters.
Thewlis captured Lupin’s contradictions beautifully – a man who preached acceptance while struggling to accept himself, who found joy in teaching despite his own inner torment. His scenes teaching Harry the Patronus charm showed rare tenderness in the increasingly dark series.
Outside Hogwarts, Thewlis has built an impressive career in films like “Wonder Woman,” “The Theory of Everything,” and “Fargo.” Also an accomplished novelist, his versatility as both villain and hero in various projects showcases the range that made his Lupin so compelling.
18. Kenneth Branagh: Lockhart’s Dazzling Fraud
With blinding smile and boundless vanity, Branagh’s Gilderoy Lockhart brought much-needed comic relief to “Chamber of Secrets.” His portrayal of the fraudulent celebrity wizard balanced humor with just enough menace to make his eventual comeuppance satisfying rather than merely silly.
Branagh’s own credentials as a Shakespearean actor and director added delicious irony to his performance as a talentless fraud. His Lockhart captivated with flamboyant robes, excessive self-promotion, and increasingly desperate attempts to maintain his facade of competence.
Already a five-time Oscar nominee before Potter, Branagh has continued his remarkable career both acting and directing, from Marvel’s “Thor” to his autobiographical “Belfast,” which won him an Academy Award for Best Original Screenplay in 2022. His brief but memorable Potter role remains a fan favorite.
19. Julie Walters: The Weasley Matriarch
“NOT MY DAUGHTER, YOU BI**H!” – with this fierce battle cry, Walters cemented Molly Weasley as one of cinema’s greatest mother figures. Her portrayal balanced warm hugs and hand-knitted sweaters with the ferocious protection of a mama bear when her family was threatened.
Already beloved in Britain for films like “Educating Rita” and “Billy Elliot,” Walters brought working-class warmth and authenticity to the magical world. Her scenes at the Burrow created the sense of chaotic love that made the Weasley home so appealing compared to Harry’s sterile life with the Dursleys.
Awarded a DBE (Dame Commander) in 2017 for her services to drama, Walters has overcome cancer while continuing to work in films like “Mamma Mia!” and “Paddington.” Her Molly Weasley remains the heart of Potter’s found-family theme.
20. James and Oliver Phelps: The Weasley Twins’ Mischief
Technically two actors, but inseparable as Fred and George Weasley, the Phelps twins brought essential comic relief and prankster spirit to the increasingly dark Potter world. Their synchronicity and genuine brotherly chemistry made the twins’ mischievous business ventures and loyalty to Harry completely believable.
Interestingly, the naturally brown-haired brothers spent a decade with dyed red hair for their roles. They were also right-handed in real life but played left-handed wizards, adding another layer of skill to their performances.
Since Potter, they’ve acted in separate and joint projects while remaining popular convention guests. They host a travel podcast called “Normal Not Normal” and maintain close friendships with their Potter castmates, particularly with Bonnie Wright who played their on-screen sister.
21. Richard Harris: The First Dumbledore
Though he appeared in only two films before his passing in 2002, Harris’s gentle, twinkle-eyed Dumbledore remains beloved by fans. His interpretation captured the headmaster’s whimsical wisdom and grandfatherly affection that made his character so appealing in the early books.
Already a legendary actor with two Oscars to his name, Harris initially declined the role, only accepting after his 11-year-old granddaughter threatened never to speak to him again if he didn’t play Dumbledore. At 72, ill with Hodgkin’s disease during filming, he extracted a promise from producers to recast if he couldn’t continue.
Harris’s legacy extends far beyond Potter – from his musical career (he had a hit with “MacArthur Park”) to iconic roles in “Camelot,” “The Field,” and “Gladiator.” His brief but impactful Dumbledore performance set the foundation for the character.
22. Timothy Spall: Pettigrew’s Ratlike Treachery
Hunched shoulders, nervous twitches, and perpetual cowering – Spall physically transformed into the animagus Peter Pettigrew, aka Wormtail. His performance perfectly captured the pathetic nature of a man who betrayed his friends out of cowardice rather than conviction.
Spall’s brilliance lay in making Pettigrew simultaneously despicable yet pitiable. His nervous mannerisms and physical transformation echoed his rat animagus form, creating a visual character study in weakness and opportunism.
Outside the wizarding world, Spall has enjoyed a distinguished career working with directors like Mike Leigh and Tim Burton. His versatility has allowed him to play everything from Winston Churchill to painter J.M.W. Turner (earning BAFTA and Cannes awards for the latter). His Pettigrew remains one of cinema’s most effectively sniveling traitors.
