Montgomery Tully, that phenomenally fast British directing machine, whipped up another espionage programmer with 1964's Master Spy. Stephen Murray stars as a Russian scientist who escapes from a Communist prison to go to work for the British. Despite his seeming sincerity, Murray's superiors suspect that he's a "plant," sent to monitor nuclear secrets on behalf of the Reds. It's more complex than that: Murray is a British spy, posing as a Russian defector, posing as a possible informer.... While only 71 minutes, Master Spy has enough plot twists for a library-full of Fleming and LeCarre. ~ Hal Erickson, Rovi
