"First and foremost, [Bowie]'s just a terrific actor. He's just brilliant in the film. He plays Tesla with a Serbian accent and he's really convincing. Most of all, I think I remember just having so many laughs. He's very, very funny and we enjoyed each other's company a lot. There were some times there were a lot of giggles going on. He's a really funny man."
Andy Serkis, Cinema Confidential, 20 October 2006
