Behind the Bastards has an episode about Jim Caviezel, and in it they discussed several anonymous and one non anonymous retelling of working with the man. If the allegations are to be believed, he kept being worse and worse not understanding his characters motivations, and they had to adjust some stuff to stop him ruining the show. They mention him doing stuff like actually harming other actors/stunt doubles if he was doing action scenes, a desire to just kill and shoot up enemies, and being really bad later on about following the script.
