Mr. Shatter (Stuart Whitman) is an international assassin, hired to bump off a top government official. He is compelled to fend off a host of Oriental kung-fu and karate experts. Peter Cushing and Anton Diffring make brief appearances. The film -- shot simultaneously with Legend of the Seven Golden Vampires, which also co-starred Peter Cushing -- was something of an experiment for the ailing Hammer studios in the mid-70s, shortly before they expired, attempting to mix an Oriental style with their own distinctly British brand of filmmaking. In most markets, Call Him Mr. Shatter was released simply as Shatter. ~ Hal Erickson, All Movie Guide
