Karl Malden (1912-2009)

Never a classic leading man, but nevertheless one of the great actors of the 1950s, an Oscar-winner for "A Streetcar named Desire", a fantastic voice and greatly underrated. A few favourites include Streetcar, Hitchcock's "I Confess", "Baby Doll", "Pollyanna" (nostalgia central, I'm afraid) and "Dead Ringer" with Bette Davis.
