Didn't even realise this was the same guy who played Yuri Boyka, and I loved UNDISPUTED. I think that's the best element of an actor, to play different characters and get in the zone of what they're like as a character.
The accent, the dialect, the theme, I really did feel like Adkins make me feel like he was a totally new guy when I watched it in one go. Cain feels very raw, and unlike other films where you're expected to accept they are as they are, I can understand and see how he evolves throughout the film.
I could watch it multiple times.
