44-year-old Jonny Lee Miller agreed to reprise his role as Simon ?Sick Boy? Williamson in ?T2 Trainspotting? because he has faith in Danny Boyle. ?I feel confident. No, not confident, but I feel good about the film. I do find it hard to be objective, because I'm pretty critical of myself. But I think people are going to enjoy it for different reasons than they expect,? Miller said. "The first film is about frustration and anger and rebellion. It's about youthful energy. You can't make a movie about a bunch of guys in their forties and have it be about that.?
