Though
Roger Moore was born in England and established himself as star of the British TV series
The Saint, Crossplot represents Moore's very first British theatrical film. He stars as an advertising executive swept up in a plot to murder a visiting African statesman. Lensed in "swinging" London, the film is "mod" to an almost depressing degree, obscuring what is at base a solid espionage thriller. Moore ultimately thwarts the villains by decoding a message secreted in a crossword puzzle -- hence the film's title. A climactic shootout in Hyde Park tops this dry run for
Roger Moore's subsequent stint as James Bond. ~ Hal Erickson, All Movie Guide
