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.
We all say we're going to quit occasionally. I'd like to have been more adventurous in my career. But it's a fascinating and not ignoble profession. No one lives more lives than the actor. Movie making is like geometry and I hated maths. But this kind of jigsaw I relish. When I played Lord Nelson I worked the poop deck in his uniform. I got extraordinary shivers. Sometimes I felt like I was staring at my own coffin. I touched that character. There lies the madness. You can't fake it.
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.
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).
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.
