Dern, Bruce (1936)

Actor. Blessed with steely eyes and a toothy grin, Dern was typecast early in his eclectic career into playing a succession of nervy psychos and losers. Even after meatier leading roles started coming his way in the 70s, his Western appearances remained in the realm of villainy, though the amiable Jack Straw-horn who is Posse's lesser evil and the eponymous outlaw of Harry Tracy represent somewhat more sympathetic characters than that of the man who shot John Wayne in the back in The Cowboys.
