Known for Acting

Kenneth Mars (April 4, 1935 – February 12, 2011) was an American actor. He appeared in two Mel Brooks films: as the deranged Nazi playwright Franz Liebkind in The Producers (1967) and Police Inspector Hans Wilhelm Friedrich Kemp in Young Frankenstein (1974). He also appeared in Peter Bogdanovich's What's Up Doc? (1972), and Woody Allen's Radio Days (1987), and Shadows and Fog (1991). Mars appeared in two seasons of Malcolm in the Middle as Otto Mannkusser, Francis's well-meaning but dimwitted boss and a German immigrant who owns a dude ranch. He voiced King Triton, Ariel's father, in the 1989 Disney animated film The Little Mermaid and its sequel, as well as its companion television series, and the Kingdom Hearts series. He also did several other animated voice-over film roles such as Littlefoot's grandfather in the Land Before Time series (up to 2008) and that of Professor Screweyes in We're Back! A Dinosaur's Story (1993), and King Colbert (Prince Cornelius's father) in Thumbelina (1994).
