Everyone plays their own crucial part towards the film.

I like the dueling club scene, where Daniel and I fight with our wands. I thought it was a brilliant scene to shoot. I think the end product looked really good.

Harry and Draco have a very weird love/hate relationship.

I used to have all the Goosebumps books as a kid too.

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.

[Julian Albert] is a CSI investigator; a forensic expert with similar skills to Barry, which gives them a different relationship to, I think, anyone else that he works with, because they're sort of treading on each other's toes in their field of expertise.

I want to take a few years out, maybe make a couple of more films or whatever.
