Actor Lloyd Bochner, best known for his roles as Cecil Colby on “Dynasty” and in the classic “To Serve Man” episode of “The Twilight Zone,” died Oct. 29 of cancer in Santa Monica, Calif. He was 81.

A memorial service will be held Nov. 10 at the Leo Baeck Temple, 1300 N. Sepulveda Blvd., Los Angeles.

Bochner’s career in television and film spanned more than five decades. He was a character actor who “almost always played a suave, handsome, wealthy villain,” said his son, Paul Bochner.

Bochner began his career on the radio in his native Ontario, Canada when he was 11. He went on to perform on stage and screen, earning two Liberty Awards, Canada’s top acting honor.

He started working in New York in 1951and moved to Los Angeles in 1960 to co-star in the television series, “Hong Kong.”

In 1963, Bochner starred as a government cryptographer in “The Twilight Zone” episode “To Serve Man,” which TV Guide ranks No. 11 in its “100 Greatest TV Episodes of All Time.”

He also appeared in such films as “The Detective” and “Tony Rome,” both with Frank Sinatra, and “The Night Walker” with Barbara Stanwyck. Other films included “The Man in the Glass Booth,” “Point Blank” and “Naked Gun 33 1/3.”

His television work included appearances in “Columbo,” “Mission: Impossible,” “McCloud,” “Wild, Wild West,” “Battlestar Galactica” and “Designing Women.”

In 1998 he co-founded the Committee to End Violence to address the impact of violence in TV and movies on popular culture. Bochner was also active in the Association of Canadian Radio and Television Artists.

In addition to his son Paul, he is survived by his wife, Ruth; son Hart, an actor, and a daughter, Johanna Courtleigh.
