With fellow producer John Daly, Hemmings formed the production company Hemdale in the early 1970s. Hemdale was responsible for many notable films, including John Schlesinger's "The Falcon and the Snowman," Gillian Armstrong's "High Tide" and Denzel Washington's film debut "Carbon Copy."

Hemmings then worked on some of the biggest TV hits of the 1980s including "Magnum PI," "The A Team," "Airwolf" and "Quantum Leap."

"People thought I was dead. But I wasn't. I was just directing The A-Team," he once remarked.

Hemmings returned to acting in the role of Cassius, in "Gladiator."

"People saw me in 'Gladiator' and said, 'He's still alive. Good Lord!' All of a sudden I've done eight pictures in the last 16 months," Hemmings said last year. "I probably won't do another until I'm 70. If I live that long."

He appeared in "Gangs of New York," "Spy Game" and "Last Orders," which also starred Hemmings' son Nolan. The father and son played the same character at different ages.

Hemmings is survived by his fourth wife, Lucy Williams, and their two children. Nolan is the only child from his second marriage, to American actress Gayle Hunnicutt. Hemmings also has a daughter from his first marriage, to Genista Ouvry, and two sons from his third marriage, to Prudence de Casembroot.

Funeral plans were not immediately announced.
