Walter Slezak

Actor · Died April 21, 1983, aged 80 · Vienna, Austria

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 1944 Lifeboat, but occasionally he got to play lighter roles, as in 1962's The Wonderful World of the Brothers Grimm. He also played a cheerfully corrupt and philosophical private detective in the 1947 film noir Born to Kill and appeared as Squire Trelawney in the 1972 version of Treasure Island.

Percentiles are each film's standing among all films on MovieCove; the typical film is the median, so one outlier cannot drag it. Percentiles and reviewer scores count the films IMDb credits them on, for now; the Midcredits score bands, the shape of the crowd and the two cards count their MovieCove titles, shows included (a show ranked among shows), appearances as themselves left out. A descriptor is the shape of a title's IMDb rating distribution against the catalog; "most divisive" needs a spread wider than half of all titles, and a card names only a principal credit: a craft role, and on a show a crew role or a run of episodes, never a courtesy credit or a one-off guest spot.
