In my opinion, Karl Urban is the real deal in this film. Yes, they could have chosen a handsome, handsome guy more similar in appearance to the game Johnny. Instead, they went with a rather brutal actor, who is essentially Johnny Cage. I liked his take on the character; it felt fresh.
I really like this actor, although you don't often see him in leading roles. But I think with this role, the role of Dredd and Billy the Butcher, he proved that he is a true professional bada$$
