In addition to a number of well known rolls: one movie that he was particularly great in was "Sorcerer" directed by Bill Friedkin 1977. If you can find it its well worth the trouble to get it and watch it! Definately a man's movie, the later parts with the journey through the jungle transporting the nitroglycerin weeping dynamite are spellbinding and spectacular.
