Secret of the Incas is a 1954 American adventure film directed by Jerry Hopper and starring Charlton Heston as adventurer Harry Steele, on the trail of an ancient Incan artifact. Shot on location at Machu Picchu in Peru, the film is often credited as the inspiration for Raiders of the Lost Ark. The supporting cast features Robert Young, Nicole Maurey and Thomas Mitchell, as well as a rare film appearance by Peruvian singer Yma Sumac. Plot American adventurer Harry Steele (Charlton Heston) earns a living as a tourist guide in Cusco, Peru but plans to make his fortune by finding the Sunburst, an Inca treasure. He possesses an ancient carved stone which gives the location of the Sunburst but has no means to travel there. He is also menaced by his dubious associate Ed Morgan (Thomas Mitchell) who wants the treasure for himself and tries to have Harry killed. When Romanian defector Elena Antonescu (Nicole Maurey) arrives, Harry apparently agrees to help her travel to Mexico so she can then get to America, but in reality he uses her situation to his own advantage. Together with Elena, he steals a plane used by a Romanian official who is attempting to get Elena to return and uses it to fly to Machu Picchu. There he discovers an archaeological expedition headed by Dr Stanley Moorehead (Robert Young), who is preparing to enter the tomb where the Sunburst is said to be located. Moorehead becomes infatuated with Elena, while Morgan arrives and coerces Harry into helping him find the treasure. While Morgan is asleep, Harry slips away and enters the tomb, locating the Sunburst hidden inside a hollow pillar. Morgan then appears and grabs the Sunburst at gunpoint before shooting his way out of the temple while being pursued by Harry and a group of locals. Trapping Morgan on a cliff edge, Harry gets the Sunburst back while Morgan falls to his death. Rather than take it for himself, he gives the Sunburst back to the local Indians who believe it must be returned to the temple.
