In 1954, the Australian journalist and author George Johnston wrote a well-researched series of biographical articles on Finch, his life, and his work, which appeared in the Sydney Sun-Herald on four consecutive Sundays, which were certainly the first detailed account of Finch's life to be published. Finch later provided the inspiration for the character Archie Calverton in Johnston's novel, Clean Straw for Nothing.
Finch co-wrote and directed an award-winning short film, The Day (1960) and announced plans to direct a feature but it did not eventuate. He won his third BAFTA for Best Actor for No Love for Johnnie (1961), although like Oscar Wilde, the film lost money. He was originally chosen to play Julius Caesar in Cleopatra (1963) and filmed scenes in London, but when the film was postponed he withdrew; the role was recast with Rex Harrison.
