This 35mm screening is part of a Unicorn Nights season at the Prince Charles. You can find the full details here.
Dirk Bogarde stars as Melville Farr, a brilliant, upwardly mobile barrister with a dark past: he's an in-the-closet gay man who risks exposure (in the days when it was illegal) by taking on a homosexual blackmail ring. It was co-written by Janet Green – a thriller/whodunnit specialist who counted Midnight Lace among her credits – and directed by Basil Dearden.What a gripping film – melodramatic and self-conscious, yes, but forthright and bold. Its tendency to show homosexuality as a tragic, pitiable quirk of nature may now look like condescension, but for the time this was real risk-taking. It has some of the earnestness of the traditional "issue" movie, but it's also a drum-tight thriller with a neat twist in the tail. Some characters, notably a kindly liberal police inspector, voice rather elaborate campaigning sentiments about how the unreformed law is just a blackmailers' charter. But there's some succinct point-making too: the same inspector, bemused by his sergeant's loathing of homosexuals, reminds him that puritanism was once against the law as well.Peter Bradshaw
