(1) What element of Harry Potter's world do you wish really existed?Rupert Grint: "The magic obviously...You could do anything, it's wicked." Emma Watson: "Magic fullstop, you know." David Thewlis: "Oh, I wish you could wave a wand and, you know get things done." Tom Felton: "You could fly on broomsticks, and you'd save pounds on petrol." (2) What actor would you love to see join the cast of Harry Potter? Rupert Grint: "I like Mike Myers." Emma Watson: "I love Renee Zellwegger...I don't quite know how we're going to fit Bridget Jones into the Harry Potter plot, that might be pushing it a bit, but she's great." (3) What would you like to see happen to your characters in the novels? Rupert Grint: "I wanted to play Quidditch once. Dan said it's really painful. Apparently in the fifth one (OOTP) Ron actually plays Quidditch, so that'll be cool." Emma Watson: "I'd quite like to see Ron and Hermione together. It's gotta happen. You know, it's there!" Tom Felton: "Epic battle at the end of the last book. Me and Harry one on one, swords in hand or something. I wouldn't mind going out in a blaze."
