Gareth Evans is, with the exception of George Miller, the finest action filmmaker working today. Both The Raid and The Raid 2 exhibit such a masterful command of action choreography that it's almost embarrassing watching some of the half-ass fight scenes in Hollywood action films afterwards.
Evans was approached for several big Hollywood movies, and there was one in particular that he came very close to making. In the end, he opted to continue to make films outside of the system, working instead with the same stunt team and the same actors that have made his films so far so compelling. He's been gearing up for his next film, Blister, for a while now, and I'm dying to see whatever it is.
