Christopher Trumbo (September 25, 1940 – January 8, 2011) was an American television writer, screenwriter and playwright. Trumbo was considered an expert on the Hollywood blacklist during the McCarthy era. His father, screenwriter Dalton Trumbo, was blacklisted by Hollywood for nearly a decade for refusing to testify to Congress, as one of a group known as The Hollywood Ten.
Trumbo was born on September 25, 1940, to Dalton and Cleo Trumbo. He was raised in Los Angeles. Trumbo was seven years old when his father was called before the House Un-American Activities Committee in 1947. His father spent ten months in prison before being released in 1951. The family moved to Mexico City to share a place with the screenwriter Hugo Butler, who was also blacklisted, and his family. The Trumbos returned to California after two years in Mexico and settled in Highland Park.
Trumbo graduated from Franklin High School in the Highland Park neighborhood of Los Angeles. He enrolled at Columbia University. He took a year off from Columbia to work as an assistant director on the 1960 film Exodus, which was written by his father, Dalton Trumbo, and directed by Otto Preminger. Trumbo received a bachelor's degree from Columbia University in 1963.
Trumbo began working as a television and film screenwriter in 1967. Trumbo co-wrote the film The Don Is Dead (1973), starring Anthony Quinn, as well as the John Wayne film Brannigan (1975). In 1974, he was the co-creator with Michael Butler of the short-lived ABC police drama Nakia, and he also wrote for the series. In 1978, Trumbo wrote the television film Ishi: The Last of His Tribe, in which he co-credited his father, who died in 1976.
