Check out what these 12 Harry Potter child actors are up to now

Apart from smashing box office records, the Harry Potter saga influenced an entire generation. The 8 movies were watched by both young and old, and continue to win new fans every time they're aired on TV.

The movies also shot some unknown, novice actors to fame. Some of the cast spent over 10 years on the set and since filming stopped, they've all grown up and their lives have changed dramatically. Here's what's happened to a few of them...

1. Joshua Herdman, who played Gregory Goyle
