LONDON, ENGLAND - JULY 07: JK Rowling, Emma Watson, Jason Isaacs and Daniel Radcliffe look on as Rupert Grint speak to the fans on stage during the World Premiere of Harry Potter and The Deathly Hallows - Part 2 at Trafalgar Square on July 7, 2011 in London, England.

15 years have passed since Daniel Radcliffe appeared in "Harry Potter and the Sorcerer's Stone" with that lightning-bolt-shaped scar on his forehead.

Since then, he's grown up, defeated Voldemort, and gone on to act in a bunch of other different movies.

Here's what the main child actors looked like when they were first introduced in the "Harry Potter" movie series, and what they look like now.
