LSD is the weapon for world domination in this pleasant Eurospy, though given the subject matter; it’s a little surprising that there’s nothing regarding the rise of the hippie culture. It is mildly entertaining to watch some of the actors do their best to appear as if they are tripping out on LSD; some of the resulting low budget hallucinatory images and music nearly put this in horror territory.
The agent, Rex Miller, played by Guy Madison, is usually pretty calm and collected, with a few interesting character quirks like sporting a long running gag of never lighting his cigarette. The score feels pretty cool and appropriate, but the spy devices are a little on the unimpressive side; though a surgical operation to insert a transmitter into Miller’s neck is a little uncomfortably gory for its time.
Further incentive to see this is Luciano Rossi in the role of a hitman.
