Movie villain Jack Palance, who won an Oscar for best supporting actor in 1992 for City Slickers, then dropped to the stage and performed one-armed push-ups at age 73 after receiving it, died Friday in Montecito, CA of natural causes. His menacing presence terrified audiences in dozens of films, including Sudden Fear, Shane, Kiss of Fire, and The Big Knife. He debuted in films in 1950 and made his last appearance in the 2004 TV movie, Back When We Were Grownups, as a 100-year-old man.
