Karl Dane (born Rasmus Karl Therkelsen Gottlieb, 12 October 1886 – 14 April 1934) was a Danish-American comedian and actor known for his work in American films, mainly of the silent film era. He became a star after portraying “Slim”, a supporting role in one of the most successful silent films of all time, The Big Parade (1925), directed by King Vidor and starring John Gilbert.

Karl Dane’s rapid career decline, depression and subsequent death have been cited as an extreme example of the fate that befell many silent film stars who were unable to make the transition from silent to sound films.
