He was soon cast in his first British movie, playing a murderous actor in Train of Events (1949). Critic C. A. Lejeune praised his work in the London Observer commenting that he "adds good cheekbones to a quick intelligence and is likely to become a cult, I fear." The Scotsman said "he should be regarded as one of the most hopeful recruits to the British screen."
Finch's next three films saw him support notable female stars: Sophia Loren in Judith (1966), Melina Mercouri in 10:30 P.M. Summer (1966) and Julie Christie in Far from the Madding Crowd (1967). He was reunited with Aldrich for The Legend of Lylah Clare (1968). The Red Tent (1970) was an expensive international adventure film, with Finch as Umberto Nobile.
George Finch was born in New South Wales, Australia, but was educated in Paris and Zürich. He was a research chemist when he moved to Britain in 1912 and later served during the First World War with the Royal Army Ordnance Depot and the Royal Field Artillery. In 1915, at Portsmouth, Hampshire, George married Alicia Fisher, the daughter of a Kent barrister. However, George Finch was not Peter Finch's biological father. He learned only in his mid-40s that his biological father was Wentworth Edward Dallas "Jock" Campbell, an Indian Army officer, whose adultery with Finch's mother was the cause of George and Alicia's divorce, when Peter was two years old. Alicia Finch married Jock Campbell in 1922.
In 1953 he appeared in his first Hollywood movie, Elephant Walk (1954), shot in Ceylon and Los Angeles. The circumstances of production were turbulent; filming started with Vivien Leigh in the lead but she had a nervous breakdown during production and had to be replaced by Elizabeth Taylor. The experience helped sour Finch on a Hollywood career and he would only work occasionally there for the rest of his career.
In 1980, American author Elaine Dundy published a biography of Finch titled Finch, Bloody Finch: A Biography of Peter Finch. That year, his second wife, Yolande Finch, also published a posthumous account of their life together, Finchy: My Life with Peter Finch. Another biography had previously been published by his friend and colleague Trader Faulkner, in 1979.
The number of Race to Dubai points available in the last three events of the season was increased, and the field size reduced. The aim was to make more players still have a chance of winning the Race to Dubai entering the final events. In addition, although the prize money was not increased, the bonus pool of US$5m would now be split among the top five players rather than the top ten. The money saved from restricting field sizes was used solely to increase the first prizes, which means that the tournaments would not have the standard prize fund distribution, and the DP World Tour Championship, Dubai would have the largest tournament first prize in golf of US$3m.
