The Silencers is a 1966 spy comedy directed by Phil Karlson and stars Dean Martin as Matt Helm, a former superspy who comes out of retirement to foil a plot by an evil organization to incite a nuclear war. The film was released at the height of the James Bond phenomena and its success spawned three sequels: Murderers' Row, The Ambushers and The Wrecking Crew.
Despite the serious tone of the original Donald Hamilton novels which these are very loosely based, this film series were made as parodies of the James Bond genre, akin to James Coburn's Flint film series.
The following weapons were used in the film The Silencers:
Smith & Wesson 39
What appears to be a customized Smith & Wesson 39 pistol is given to Matt by MacDonald (James Gregory). The pistol has a unique reverse barrel that actually shoots the round at the person holding the weapon. The pistol also is seen in the hands of both Sam Gunther (Robert Webber) and Gail Hendricks (Stella Stevens).
The Madsen M50 is one of the weapons carried by the Big O guards. The Madsen also is used by Matt and Gail.
