This entertaining spy comedy marks the first appearance of suave secret agent Al Pereira, portrayed here by actor-singer
Eddie Constantine, best known as the similar Lemmy Caution in
Alphaville and other films. Cult director Jesus Franco's final black-and-white film has Pereira on the trail of robotic hitmen murdering a series of important people. The agent romances a go-go dancer (Sophie Hardy) and breaks a Chinese espionage syndicate headed by the wily Lee Wee (Vicente Roca) before being kidnapped. The real culprits are Sir Percy (
Fernando Rey) and his lover Lady Cecilia (Francoise Brion), who plan to turn their Rh-negative victims, including Pereira, into robot assassins. This clever, fast-paced adventure was revamped by acclaimed screenwriter Jean-Claude Carriere, whose witty dialogue enhances the film greatly. The Al Pereira character returned in Franco's Les Ebranlees (1972) and numerous other films. ~ Robert Firsching, All Movie Guide
