THE SILENT ENEMY is a fine WW2 movie of the kind the British used to make so well. This one boasts an interesting, fact-based story about a little known theatre of war and an exceptional ensemble cast who really bring life to the various roles. Laurence Harvey plays an enthusiastic young officer who is shipped off to Gibraltar to help combat the threat of Italian frogmen who have been mining and destroying Allied shipping trying to access the Med.
Harvey, who sports stubble and blond hair in this film, is playing the real-life wartime diver 'Buster' Crabb, the man who died in mysterious circumstances shortly before this film was made. Harvey usually plays insufferable characters but he's very good here, strong-willed and perfectly heroic. I'm not usually a fan of underwater-themed movies as I found they're usually let down by lacklustre underwater photography, but this film's different; the action scenes are highly suspenseful and complimented by strong special effects work.
I liked the way that THE SILENT ENEMY is a film that focuses on technology and the apparatus of war while being readily accessible to the layman viewer at the same time. The supporting cast includes a great role for Sid James who brings some of his dry humour to a serious production and the likes of Michael Craig, Dawn Addams, Nigel Stock, and David Lodge. I was also pleased to see a bunch of youthful and famous Italian actors playing their countrymen: Gianna Maria Canale, Massimo Serato, and Giacomo Rossi-Stuart are all present here before they became big faces in Italian genre cinema of the 1960s.
