Yeah especially when he shares the screen with the guy who played Saladin and David Thewlis.

I think in the first act of the movie it somehow make sense for him to be "wooden" he pretty much doesn't want to live but when he arrives at Jerusalem he doesn't portray much more emotions.

I think a better actor would have elevated that movie even more. someone like Gyllenhall, Colin Farrell or Christian Bale (bit older)
