1968's French-Italian "OSS 117 Double Agent" aka "OSS 117 Murder for Sale" (Pas de Roses pour OSS 117 or No Roses for OSS 117) was the 5th entry in the 60s OSS series, director Andre Hunebelle at the helm for the 4th time, location shooting in Rome and Tunisia. The first two actors cast as Hubert Bonisseur de La Bath aka OSS 117, Kerwin Mathews and Frederick Stafford, both played the role twice, the latter unavailable as he was busy filming Alfred Hitchcock's "Topaz." By sheer coincidence, the one chosen to replace Stafford for this lone entry was "Psycho" leading man John Gavin, just good enough to catch the attention of producer Albert Broccoli until Sean Connery returned to the 007 fold for "Diamonds Are Forever." Perhaps the finest cast assembled for any OSS title begins with luscious Luciana Paluzzi, only three years removed from the biggest Bond blockbuster, "Thunderball," Curt Jurgens still a decade away from Roger Moore's "The Spy Who Loved Me," add Margaret Lee as leading lady and a regrettably brief naked cameo from Rosalba Neri for additional eye candy, plus the welcome return of villainous Robert Hossein (from "Shadow of Evil"), and there are the makings of a film almost as good as Stafford's "OSS 117 Mission for a Killer." Hubert impersonates a notorious assassin to infiltrate 'The Organization,' keeping their paid killers in line via a slow acting poison, for without the antidote administered by Hossein's cold hearted Dr. Saadi they are certain to perish. Curt Jurgens is in familiar form as the criminal mastermind known as 'The Major,' George Eastman his main henchman, assisted by beautiful doctor Luciana Paluzzi, who sadly vanishes from the picture after the phony 'vaccine.' Hubert's assignment is to cause a rift between warring tribes eager to sign a peace treaty, foiling the plot by kidnapping the intended victim and replacing his 'corpse' prior to the fatal explosion, Margaret Lee a delightful love interest and damsel in distress (apparently on loan from Harry Alan Towers). The plot tends to move in fits and starts, one impressive early scene with Hubert forced to fight while preserving his unclothed modesty, the climactic rooftop skirmish falling short much like its wicked protagonist (a soft jazzy music score is no help either). This 60s series could not lay claim to be classics but they weren't cheap ripoffs either, just diverting enough to offer solid fare for undiscriminating viewers.
