Alfred Hitchcock hadn't made a spy thriller since the 1930s, so his 1969 adaptation of Leon Uris's bestseller seemed like a curious choice for the director. But Hitchcock makes Uris's story of the West's investigation into the Soviet Union's dealings with Cuba his own. Frederick Stafford plays a French intelligence agent who works with his American counterpart (John Forsythe) to break up a Soviet spy ring. The film is a bit flat dramatically and visually, and there are sequences that seem to occupy Hitchcock's attention more than others. A minor work all around, with at least two alternative endings shot by Hitchcock. --Tom Keogh
