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."
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.
During his war service Finch was given leave to act in radio, theatre and film. He appeared in a number of propaganda shorts, including Another Threshold (1942), These Stars Are Mine (1943), While There is Still Time (1943) and South West Pacific (1943), the latter for Ken G. Hall. He also appeared in two of the few Australian feature films made during the war, The Rats of Tobruk (1944) and the less distinguished Red Sky at Morning (1944).
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.
