The Hand has a grisly premise and a seedy atmosphere but the film loses its way with a talky confused script, uninteresting characters, and poor acting.
Starting in 1940s Burma, the story sees three captured British soldiers being interrogated by the Japanese. When two of them each have a hand chopped off, the third agrees to talk. Cut to 1960s London and a policeman makes a gruesome discovery - a tramp who is missing a hand - is there a link back to the events in the Far East?
The majority of the film is taken up with the police investigation involving Inspector Munyard and his sidekick Sergeant Foster, two solid, characterless, permanently smoking detectives. The investigation mostly consists of the two of them talking, going to places, talking some more, and then smoking, which does not make for gripping cinema. It is not helped by the poorly written script, which feels like a great central premise that nobody knew how to write a pay-off for. The fractured, hard to follow storyline feels like certain key expositional scenes were either not written, not filmed, or cut out.
Having said that there is, for the time it was released, occasional brutal (if off screen) violence, and some surprisingly coarse language. The Hand also has a rather pleasing ambience of Trad Jazz, fog and Brylcream, so if those things appeal, come for the story, stay for the atmosphere.
