Simon Charles Pendered MacCorkindale (12 February 1952 – 14 October 2010) was a British actor, film director, writer and producer. MacCorkindale spent much of his childhood moving around due to his father's commission with the Royal Air Force. Poor eyesight prevented him following a similar career in the RAF, so he instead planned to become a theatre director. Training at the Theatre of Arts in London, MacCorkindale started work as an actor, making his West End debut in 1974. He went on to appear in numerous roles in television, including the series I, Claudius and Jesus of Nazareth, before starring as Simon Doyle in the film Death on the Nile (1978). This proved to be a breakthrough role and allowed MacCorkindale to move to the United States, where he appeared in a variety of films and TV series including Quatermass (1979), The Riddle of the Sands (1979), The Sword and the Sorcerer (1982) and Jaws 3-D (1983).
In 1983, MacCorkindale starred in the short-lived series Manimal as the lead character, Dr Jonathan Chase, before taking up the longer-running role of lawyer Greg Reardon in Falcon Crest. Throughout the late 1980s and 1990s he directed and produced many stage, TV and film productions through his company Amy International Artists, such as the film Stealing Heaven (1988). Moving to Canada, MacCorkindale starred as Peter Sinclair in the series Counterstrike for three years. He returned to the United Kingdom in 2002 and joined the cast of the BBC medical drama Casualty, appearing in the role of Harry Harper for six years until 2008. He married actress Susan George in 1984 and died of colorectal cancer in 2010.
MacCorkindale was diagnosed with bowel cancer in 2006, and underwent an operation to remove a section of his bowel during a two-week break from filming Casualty. Although the cancer was excised and MacCorkindale went into remission following the surgery, one year later doctors discovered that the cancer had metastasised to his lungs. MacCorkindale continued to act during his treatment, returning to film his final series of Casualty in late 2007; he did not disclose his illness to his colleagues, and found it surreal when scripts required his character to inform patients that they had cancer or another incurable disease. MacCorkindale spent much of his fortune on private cancer treatment in the United States, with limited success. In November 2009, he publicly revealed that the disease was terminal, and he died on 14 October 2010 at a clinic in London.
