He's always been a bully. He bullied Michael J. Fox and other actors
during the filming of Casualties of War in 1988. He was indistinguishable from his character in the movie, an angry, bigoted, arshole of a sargeant who bullied his soldiers and behaved cruelly all the time. According to Biran DePalma, director of the movie, he was exactly like his character and he would never talk to Michael J. Fox who's known to be a nice guy. Why's that? How can anybody in their right mind admire this arrogant arshole who flirts with leftist dictators while he criticises US involvement in wars? What a bloody hypocrite wuss.
