Sitting Target is a picture of brutish violence. Its story of a British prison break by a hardened, jealousy-ridden convict to kill the wife he believes unfaithful has been recounted with no holds barred.The screenplay [from a novel by Laurence Henderson] sometimes is difficult to follow, but Douglas Hickox’ tense direction keeps movement at top speed. Obsession of con to get to his wife, who has revealed she is pregnant and wants a divorce, is a motivating theme – built with growing suspense. Jill St John becomes the sitting target for Oliver Reed as the convicted murderer who smashes his way to freedom and stalks his prey. Actual scenes lensed in two Irish prisons give film a grimly authentic atmosphere and the escape of Reed and two other cons is spectacularly depicted.
