Walter Slezak (3 May 1902 – 21 April 1983) was a portly Austrian character actor who appeared in numerous Hollywood films. Slezak often portrayed villains or thugs, most notably the German U-boat captain in Alfred Hitchcock's film Lifeboat (1944), but occasionally he got to play lighter roles, as in The Wonderful World of the Brothers Grimm (1962). He also played a cheerfully corrupt and philosophical private detective in the film noir Born to Kill (1947) and appeared as Squire Trelawney in Treasure Island (1972). Born in Vienna, Austria, the son of opera tenor Leo Slezak, he studied medicine for a time and later worked as a bank teller. He was talked into taking his first role, in the 1922 Austrian film Sodom und Gomorrah, by his friend and the film's director, Michael Curtiz. In his early movie career, before he gained a great deal of weight, Slezak was cast as a thin leading man in silent films. He also acted on the stage for many years, debuting on Broadway in 1931. His first American film was Once Upon a Honeymoon (1942), with Ginger Rogers and Cary Grant.
