John Hoyt
John Hoyt was an American film, theatre, and television actor, October 5, 1905 – September 15, 1991. He began his acting career on Broadway, later appearing in numerous films and television series.
He is perhaps best known for his roles in the films The Lawless (1950), When Worlds Collide (1951), Julius Caesar (1953), Blackboard Jungle (1955), Spartacus (1960), Cleopatra (1963), The Outer Limits (1964), Flesh Gordon (1974), and the television series Gimme a Break! (1981-87).
Hoyt was born John McArthur Hoysradt in Bronxville, New York, the son of Warren J. Hoysradt, an investment banker, and his wife, Ethel Hoysradt, née Wolf. He attended the Hotchkiss School and Yale University, where he served on the editorial board of campus humor magazine The Yale Record. He received a bachelor's and a master's degree from Yale. He worked as a history instructor at the Groton School for two years.
Hoyt shortened his surname in 1945, the year before his film debut in O.S.S. He became a familiar face in film noir and played the strict Principal Warneke in the 1955 film Blackboard Jungle, starring Glenn Ford. He played an industrialist in the 1951 film When Worlds Collide. Hoyt appeared in one Shakespearean film: MGM's Julius Caesar, reprising the role of Decius Brutus (or Decimus Junius Brutus Albinus), whom he had played in the 1937 Mercury Theatre production. In 1952, he played Cato in Androcles and the Lion. In 1953, he portrayed Elijah in the biblical film Sins of Jezebel. He had featured roles in the big-budget sixties epics Spartacus and Cleopatra.
