Born in Ely, Cambridgeshire, England, the light-haired, aristocratically handsome Simon MacCorkindale's first career choice was to follow in his Air Force pilot father Peter's footsteps by joining the Air Training Corps, but his deteriorating eyesight forced him to choose an alternative vocation. Taking drama classes following high school graduation, he attended the highly prestigious Haileybury and Imperial Service College in Hertfordshire in the late 60s. He subsequently put in much time on the repertory theatre stage, which culminated in a West End debut.
Divorced during his early career from actress Fiona Fullerton, he subsequently married actress Susan George and produced a few of her films. They also raised Arabian horses. He focused for a time as a producer/director/writer on a variety of personal projects, but returned again to performing. Simon lost his more than four-year battle with bowel cancer in October 2010.
