M.A.S.H. is the only movie I know him from.
I kind of liked Steelyard Blues, at least when I first saw it in the 70s. Peter Boyle was a lot better in it than Donald Sutherland, though. Jane Fonda contributed nothing to that movie.
Kelly’s Heroes. Another nutcase portrayal of an American GI by a canadian.
Odd, but I just saw him tonight on Prime in a 2012 movie, “Assassin’s Bullet”, with Christian Slater as the hero.
Had no idea he was a commie.
He is also in one of my favorite movies “The Dirty Dozen,” which I still watch occasionally. I hold my nose and enjoy it in spite of him being in it.
