A great job by Stanley Kramer on this film. Tony Curtis and Sidney Poitier turn in stellar performances as two convicts who get an unexpected shot at escape but are held together by a length of chain. They must learn to overcome their racial dislike of each other in order to survive and gain their freedom. But will they? The film is shot in black and white and had it been shot in color it would not have been as good. A remake was done some years later which was passable but didn't match this original version.
