A spaghetti Western, and a pretty absurd one. Nero, sporting more costumes than expressions, is a Swedish gunrunner in a straw boater who gets mixed up with hidden treasure and communist revolutionaries down Mexico way. Palance, startlingly like Robert Shaw on a bad day, is a slant-eyed mercenary with a pet hawk and an artificial hand who's pissed at Nero for leaving him nailed to a tree in Cuba. Rey, minus his own voice, is a bespectacled commie professor who advocates Gandhi-esque non-violence but graduates to some serious slaughter by the end. Twangy Morricone score.
