work in Germany returned to programmers like those that had begun his career in Hollywood 23 years earlier. From 1964 to 1965, he made a series of films with former Tarzan Lex Barker: The Shoot, The Treasure of the Aztecs, and The Pyramid of the Sun God, all taken from the western, adventure novels of Karl May. Later career Siodmak's return to Hollywood filmmaking in 1967 with the wide-screen western Custer of the West was another disappointment, receiving mostly negative reviews from critics and failing to generate box-office appeal. Siodmak ended his career with a six-hour, two-part toga and chariot epic, Kampf um Rom (1968), a more campy work (perhaps intentionally) than Cobra Woman had been. There was a brief and profitable foray into television in Great Britain with the series O.S.S. (1957–58). Siodmak was last seen publicly in an interview for Swiss television at his home in Ascona in 1971. He died alone in 1973 in Locarno of a heart attack, seven weeks after his wife's death. The British Film Institute held a retrospective of his career in April and May 2015.
