I've always liked David Warner (Irenicus) for his voice. It's too bad that he doesn't receive more recognition in films, and he almost always plays the regal/sinister/envoy character type. He was in two Star Trek films (as different characters! in VI he was the Klingon ambassador who gets killed with the gravity system down). Unfortunately, I also recollect him as the nerdy scientist in Teenage Mutant Ninja Turtles II (so sad). Does anyone know other films he's been in?
