I think there were a few things that really interested me. One was that I didn't know a lot about hooligan culture. I'd heard of football violence but I didn't quite understand how intense it really is, how organized it is, and more importantly, how these people aren't necessarily criminals or thugs in their daily life. They almost have this sort of double life. They're people with families and some of them have relatively good jobs. That fascinated me. And also the opportunity of being able to take a character from that kind of relatively innocent place to essentially making him a hooligan was very attractive to me. To explore a darker side of humanity that I'd not really explored in film before just as an actor was an interesting challenge.
