With the massive exterior sets, lavish interior sets and a multitude of Asian extras left over from
Marco Polo (1962), Panda Productions had writers
Oreste Biancoli and
Duccio Tessari fashion a sword-and-sandal/mythological muscleman epic - a genre that had become highly popular around the world - placing hero Maciste in a Chinese setting. Genre specialist
Riccardo Freda was brought in to direct,
Gordon Scott was cast as Maciste (renamed "Samson" for the U.S. version) and
Yôko Tani was kept on as the female lead.
