Columbia Pictures tried to create a tongue-in-cheek American James Bond with this, the first of five motion pictures based on the character of Matt Helm, a spy created in a series of novels by Donald Hamilton. Dean Martin stars as Helm, a boozing, womanizing cad of a spy coaxed out of retirement by ex-girlfiend Tina Batori (Daliah Lavi). His mission: stop the evil Big O organization, whose leader, Tung-Tze (Victor Buono) schemes to sabotage an atomic missile and thus spark World War III. Producer Irving Allen had once been partners with Albert R. Broccoli in the British film production company Warwick Films, their alliance ironically disintegrating over the merits of creating a Bond series. When Broccoli's instincts proved correct, Allen attempted to create his own spy franchise with the Helm character. The sequels to The Silencers (1966) were Murderer's Row (1966), The Ambushers (1967), and The Wrecking Crew (1969). Allen unsuccessfully tried to resurrect the character as a TV movie, Matt Helm (1975). ~ Karl Williams, All Movie Guide
