The eponymous Four Just Men of this film are British World War I comrades, who reunite in peacetime to bring disaster to their country's enemies. The quartet is not above murder and sabotage to achieve their ends, but their patriotism is never in question. The goal of the heroes is to thwart a megalomaniac who plans to destroy the Suez Canal, then devastate the British empire in order to create his own world dictatorship. Francis L. Sullivan, Hugh Sinclair, Griffith Jones and Frank Lawton play the Four Just Men, though Lawton's early death reduces the ranks to three. The villainy is in the hands of Basil Sydney, who is every bit as ruthless and resourceful as the heroes. Four Just Men is based on a series of adventure novels by British "writing machine" Edgar Wallace--which also formed the basis of a 1959 TV series of the same name, starring Dan Dailey, Richard Conte, Jack Hawkins and Vittorio De Sica.
