A rather shabby American adventurer in grubby khakis and a floppy fedora seeks hidden treasures in lost civilisations. But wait this isn't Indiana Jones but Harry Steele (Charlton Heston)! Steele is a shady bum who guides/rips off tourists in a remote Peruvian town while also seeking the gold and jewel encrusted star burst from the Incan Temple of the Sun.
He needs a plane though to get to Machu Picchu, his chance comes when fleeing Romanian lovely Elena (Nicole Maurey) arrives in town. He uses her as bait to steal a plane hired by the Romanian secret service. He and Elena begin a trip through jungle and across mountains until they reach Machu Picchu. There to his dismay he finds there is already a party of archaeologists led by Dr Moorehead (Robert Young) and who have already found the tomb...
A very satisfying adventure, Heston plays Steele as a real anti-hero (though turns out to be the good guy in the end which is perhaps a bit of a cop out), he doesn't want to find the Incan relic to advance our knowledge of history but to become rich! The film is worth seeing for the number of scenes ripped off in Raiders of the Lost Ark nearly thirty years later. The rather extraordinary singing by Yma Sumac is also something which deserves a watch (or listen).
