yeah, I personally have a brown complexion but Iranians can look chinese, white, mexican, Indian, and even totally, completely black. It's obvious that the game character looked mexican though.
honestly, I'm just worried that this will suck like most video game movies (most probably with time travel used in a gimmicky way for the story). maybe the story is good and they never actually told Gyllenhaal that it is a viddy game story so he doesn't get scared of it sucking big hard balls.
