This international thriller was a unique co-production between England's Hammer Studios and the Shaw Brothers, the legendary Hong Kong producers responsible for a slew of martial arts classics. Filmed on location in Hong Kong, SHATTER stars Stuart Whitman as the eponymous assassin who finds that he is marked for death when he tries to collect payment for a hit he made on an African dictator. Forced to run for his life through the seedy underbelly of Hong Kong, Shatter is aided by a kung fu master (Lung Ti) as he tries to destroy the international drug cartel that will stop at nothing to kill him.
