Hercules and the Treasure of the Incas

Hercules and the Treasure of the Incas is a 1964 film written and directed by Piero Pierotti and starring Alan Steel. Originally conceived as a peplum film, given the contemporary success of A Fistful of Dollars, it was turned into a western film during the shootings, resulting in a bizarre crossover between the two genres. Although Alan Steel reverts to a Hercules-like character in the film's climax, the bulk of the film resembles a standard Spaghetti Western.
