Daniel Radcliffe's Age in Harry Potter and the Philosopher's Stone
Daniel Radcliffe was 11 years old when Harry Potter and the Philosopher's Stone was released in 2001. He was born on 23 July 1989, so he turned 12 during the film's theatrical run.
Filming Timeline and Casting
Principal photography for the first film began in 2000, when Radcliffe was still 10. He was cast at age 11 after auditions, and the movie premiered in November 2001.
Why Age Matters for the First Movie
Radcliffe's age matched Harry's canonical starting point as an 11-year-old entering Hogwarts. This alignment helped ground the story's transition from ordinary life to the wizarding world.
