^^Karl Urban is a fairly big name these days,...
Karl Urban is movie cancer. He is almost painful to watch and his one acting "trick" was used up in LOTR. I have seen everything he has done since and winced. Just rent his Bourne Movie, Riddick, and Pathfinder and try to make it through his scenes...i dare you. He most certainly does not have the chops to to pull off an expressive character like McCoy (or what should be an expressive character).
