I really liked the snake that breaks out of the cage in the beginning of the movie. I saw it in real life, and it was really cool. Really big and fat. The owls are cool as well, but you can't really pet them.

Draco's not really a bully. He's not exactly the biggest, strongest guy in the world. He's more a rich, snobby person. He thinks of himself as really cool.

You see another side of Draco when he's with his dad. When Draco is with his dad, he doesn't say anything. He keeps his mouth shut. He's sort of bullied by his dad, so he acts very different.

We went with the St. Lawrence Experience, which is run by Joe Babbitt, who is a close friend now. We went out there for 10 days and we had the best week of our lives, and we've been going back since. We've been back three times now.

Working with big actors and realising that they were just normal people who've got an incredible talent was just a great experience.
