Quite simply the weirdest James Mason film I've ever seen. He plays an Interpol agent in this European co-production hunting down a rogue assassin who is killing heroin pushers. Well that sounds straight forward enough.
The thing is the film is rather eccentric, and suggests that copious amounts of recreational stimulants may have been involved in it's production...
The scenes in Pakistan especially involving Jean Seberg and Stephen Boyd score highly on the strange-o-meter. Especially as the latter wanders through Pakistani villages dressed head to toe in leather and no one bats an eyelid.
The film is odd and pretty surreal, and also very violent. Some of the action scenes are pretty good, especially the car-bike chase. But ultimately the film makes little sense and has rather a stereotyped view of life in Pakistan and Afghanistan. Definitely a film of it's time.
