Scholastic has posted a new interview with James and Oliver Phelps, who play Fred and George Weasley.

Q: In the films you guys speak in unison. Does that ever happen in real life?
James: It kind of came across because of that. In the films that happened because Oliver said something and I just cut him up to carry on pretty much exactly what he was saying. And Alfonso [the director of Prisoner of Azkaban] said, “I like that. Let’s put it in.” So he literally got the script, crossed a load out and mixed it all up and it came from there. So I guess we do. I don’t know why. Probably been around each other too much. 

Q: Have you managed to take any of the props as souvenirs?
Oliver: A few may have found their way into my bag. We were on tour for the Half-Blood Prince and I was going through one airport. I took my laptop out of my bag and I found a puking pastie. And the [security] dude who was working was like, “What’s that?” And I was like, “. . . puking pastie?” And he says, “What does that do?” “It makes you sick.” “Why have you got that?” And I said, “You’re not gonna believe me if I told you.”

Q: Can you tell us any secrets about some of the stars in the film?
Oliver: [laughs] I think Rupert’s [Rupert Grint who plays Ron Weasley] math skills are something to be desired, especially if you’re playing him at a sport. We play a lot of golf and table tennis, and it’s amazing when you finish playing a hole of golf. “It was six Rupe.” And he’ll say, “No it was a four. It was a four!” And he’ll start inventing new rules like, “Oh I’m allowed to throw off the tee on every nine holes,” or something.
James: Alan Rickman [who plays Severus Snape] his deep voice and everything and the kind of character he plays, you’re quite intimidated. But he’s such an outgoing and funny guy!
