Q&A with Idris Elba
A: I've done thrillers, but they're typically of the supernatural nature. This is a human story—an ordinary man with an extraordinary story. I have to say, it's quite a challenge, keeping up that sort of angst for that amount of time. Throughout the film, my character goes through a fair amount of drama, and it takes seven, eight weeks to film. So that's a long time to keep a frown on your face.
