Remember that magical moment in November 2001 when the world first glimpsed Hogwarts on the big screen? A young boy with a lightning-shaped scar boarded the Hogwarts Express, and an entire generation fell under the spell of J.K. Rowling’s wizarding world. The harry potter 1 cast brought to life the beloved characters from Harry Potter and the Philosopher’s Stone (known as Harry Potter and the Sorcerer’s Stone in the US), launching one of the most successful film franchises in history.
Directed by Chris Columbus, this faithful adaptation became the highest-grossing film of 2001 and introduced us to an extraordinary ensemble of British and Irish talent—as insisted by Rowling herself. Whether you’re rewatching for nostalgia, introducing the story to a new generation, or curious about the actors behind the robes and wands, this comprehensive guide dives deep into the full cast of the first Harry Potter movie. We’ll explore their roles, casting stories, performances, and where they are today as of January 2026.
From the Golden Trio to the legendary Hogwarts staff, supporting families, and hidden gems, join us in celebrating the iconic stars who started it all.
The Casting Process: How the Magical Ensemble Came Together
Behind the Scenes of Casting Harry Potter’s First Film
The casting for Harry Potter and the Philosopher’s Stone was a monumental task that set the tone for the entire series. J.K. Rowling played a pivotal role, demanding an all-British and Irish cast to preserve the story’s authentic feel. She sold the film rights to Warner Bros. in 1999 for a reported £1 million, with the condition that the principal actors reflect the book’s British roots.
Producer David Heyman and director Chris Columbus faced immense pressure. Over 40,000 children auditioned for the lead roles alone through open casting calls across the UK. Hollywood stars like Robin Williams (who desperately wanted to play Hagrid) and Rosie O’Donnell (eyeing Molly Weasley) were turned away to honor Rowling’s “British only” rule.
Filming ran from September 2000 to March 2001 at Leavesden Studios, with the cast bonding closely—veteran actor Richard Harris later called it the tightest ensemble he’d ever worked with in over 40 years. Rowling personally approved key choices and even shared future plot secrets with Alan Rickman to inform his portrayal of Severus Snape.
This meticulous process ensured faithfulness to the source material, creating performances that have endured for over two decades.
Notable Audition Stories and Almost-Casts
The auditions were full of surprises and near-misses:
- Liam Aiken was nearly cast as Harry but was passed over due to his American nationality.
- Haley Joel Osment was considered early on, but the British rule prevailed.
- Tom Felton originally auditioned for Harry and Ron before landing Draco Malfoy.
- Emma Watson impressed with her confidence, while Daniel Radcliffe was discovered through a chance theater sighting after his parents initially hesitated.
- David Thewlis auditioned for Professor Quirrell but later played Remus Lupin.
- Rik Mayall filmed scenes as Peeves the Poltergeist, but they were cut entirely.
These stories highlight the serendipity and rigor that shaped the perfect cast.
The Main Cast: The Golden Trio and Core Characters
The Young Stars Who Brought Hogwarts to Life
The child actors were unknowns thrust into stardom, delivering performances that captured the wonder, friendship, and bravery at the heart of the story.
Daniel Radcliffe as Harry Potter
At just 11 years old, Daniel Radcliffe embodied the orphaned boy who lived. Discovered by producer David Heyman at a theater performance of Stones in His Pockets, Radcliffe’s parents were initially reluctant, fearing the impact on his childhood. But after persuasion, he won the role over thousands.
His wide-eyed innocence during scenes like discovering Diagon Alley or facing Voldemort made Harry relatable and heroic. The film launched Radcliffe’s career; he starred in all eight movies.
As of 2026, Radcliffe continues to thrive post-Potter. He won a Tony Award for Merrily We Roll Along and is set to star in the solo Broadway play Every Brilliant Thing starting February 2026. Recent projects include the film version of Merrily (released December 2025) and the Vietnam War thriller Trust the Man. Radcliffe has also reached out to the new HBO Harry Potter series‘ young star, Dominic McLaughlin, offering support.
Then: A bespectacled 11-year-old newcomer. Now: A versatile, award-winning actor in his mid-30s, known for eclectic roles.
Rupert Grint as Ron Weasley
Rupert Grint, then 12, won the role of Harry’s loyal best friend with a unique audition tape featuring a rap about why he should play Ron. His natural humor and freckled charm perfectly captured Ron’s wit, loyalty, and occasional insecurity.
Grint grew up on screen across the series. In 2026, he’s starring in Ti West’s Ebenezer: A Christmas Carol (releasing November 2026), reportedly as Bob Cratchit, alongside Johnny Depp. Other recent work includes Knock at the Cabin (2023) and Guillermo del Toro’s Cabinet of Curiosities. Grint, a father himself, has expressed openness to returning to the wizarding world under the right conditions and sent a supportive letter to the HBO series’ new Ron.
Then: A cheeky, red-haired kid with impeccable comic timing. Now: A seasoned actor embracing diverse genres.
Emma Watson as Hermione Granger
Emma Watson, aged 10 during filming, brought intelligence and fierceness to the bushy-haired witch. Found through school recommendations, her audition showcased poise beyond her years.
Watson’s Hermione became an icon for young girls. Post-Potter, she’s taken selective roles, focusing on activism and education (graduating from Brown University and pursuing creative writing at Oxford).
In 2025-2026, Watson has made rare public appearances, including Paris Fashion Week (Miu Miu Spring/Summer 2026 show) and Cannes. She’s involved in sustainable business (Renais gin with her brother) and environmental causes. Her last major film was Little Women (2019), but she remains influential in fashion and advocacy.
Then: A precocious bookworm with perfect pronunciation of “Leviosa.” Now: A global activist, entrepreneur, and occasional screen star.
Tom Felton as Draco Malfoy
Tom Felton transformed the sneering Slytherin into a memorable antagonist. After auditioning for the heroes, he nailed Draco’s arrogance.
Felton has embraced his Potter legacy. In late 2025, he reprised Draco on Broadway in Harry Potter and the Cursed Child, extending his run to May 10, 2026, due to demand. Upcoming films include the horror They Will Kill You (March 2026). He’s also reunited with co-stars for events.
Then: A platinum-blond bully. Now: A fan-favorite embracing nostalgia.
Other notable young actors include:
- Harry Melling as Dudley Dursley
- Devon Murray as Seamus Finnigan
- The Phelps twins (James and Oliver) as Fred and George Weasley
