Richard Arlen (born Sylvanus Richard Mattimore) was an American film and television actor. He served as a pilot in the Royal Canadian Flying Corps during World War I. After the war, he went to the oilfields of Texas and Oklahoma and found work as a tool boy. He was thereafter a messenger and sporting editor of a newspaper before going to Los Angeles to act in films, but no producer wanted him. He was a delivery boy for a film laboratory when the motorcycle which he was riding landed him a broken leg outside the Paramount Pictures lot. A sympathetic film director gave him his start as an extra. He appeared at first in silent films before making the transition to talkies. His first important film role was in Vengeance of the Deep.

He took time out from his Hollywood career to teach as a United States Army Air Forces flight instructor in World War II. Arlen is best known for his role as a pilot in the Academy Award-winning Wings with Clara Bow, Charles 'Buddy' Rogers, Gary Cooper, El Brendel, and his second wife, Jobyna Ralston, whom he married in 1927. He was among the more famous residents of the celebrity enclave, Toluca Lake, California. He married New York socialite, Margaret Kinsella, in 1946.
