MTV has a new interview with Jamie Campbell Bower, who will be playing young Gellert Grindlewald in Harry Potter and the Deathly Hallows.

MTV: We’re going to see you in “Harry Potter and the Deathly Hallows” as Gellert Grindlewald, joining Rob as the only actor to have a foot in both of these phenomenally huge franchises. Have you guys bonded over this?
Campbell Bower: Well, Rob is quite a significant character in the “Potter” movies, I believe, from what I can remember. My character is a bit smaller.

MTV: Have you and Rob discussed things he learned as he tried to go from one franchise to the other? Did he have pointers for you?
Campbell Bower: No. There isn’t much difference between them, apart from the story. They’re both massive franchises, and they both work like a machine, you know? Everyone’s on time, and everyone’s doing the best job that they can.

MTV: Some people might say that “Twilight” is more for girls, while boys enjoy “Potter” more. Would you agree?
Campbell Bower: I’d say that they’ve both got fairly specific fanbases. “Twilight” is more for your 13- to18-year-olds, although there are people who obviously enjoy it — older people — which is great. But I think the main audience is the 13- to 18-year-olds, maybe because of Rob and the fact that they love Edward. [As for] “Harry Potter,” it’s a bit younger. Although the recent films are a bit dark. I saw [a “Potter” film] the other day, and I thought it was quite scary. You’ve also got your older audience [there].

MTV: What’s the difference between how you approach each franchise?
Campbell Bower: Like, am I playing them the same? No, I mean, they’re two different characters, they’re two different people. [To play them the same] would be like, “I’ve just eaten some cheese, and now I’m eating an apple, and it tastes like cheese.” When you’re filming anything, you’ve just got to believe in the character and believe yourself that you are the character.
