He was great in Full Metal Jacket... maybe he wasn't acting?
A real life head case?
Some of these libs can really act (Deniro, Pacino, etc). But I've given up on Hollywood. I'd rather watch old movies with Jimmy Stewart, John Wayne, Bogart, etc. Back when Hollywood had a streak of patriotism, long since extinguished.
I have a great deal of trouble suspending disbelief in movies, and D'Onofrio's Pyle completely convinced me.
