Once, during work on IL FIGLIO DI SPARTACO, there was a curious episode. The scene was planned for Steve Reeves and Jacques Sernas to arrive by horse from a distant dune and do and say certain things. And from the position far away where we placed the camera, I then had to give "Action!" to the actors by radio telephone. So from the established position, the two riders came up at a gallop and arrived at the agreed point in front of us. But arriving in front of the camera were not Reeves and Sernas, but rather Rory Calhoun and another actor, also dressed as Ancient Romans, but with costumes different to those in my film.
I thought I was seeing things. And I thought it was strange when they started performing an action infront of the camera that was totally different to what I had planned. The explanation came an instant afterwards when we discovered that there was another crew a kilometer away on the other slope of the dune that was filming IL COLOSSO DI RODI, and the actors had taken the wrong direction.
Above all I was a fan of the Western and therefore my Ancient Romans were a little bit derived from the Pioneers, the Sheriffs. The sword to the side was like a gun. Indeed, it was in this way my films of the genre differentiated from those of Francisci and of Cottafavi. But then it really seemed quite proper that the Western was solely an American prerogative, and impossible to make by us.
