In 1958 Pino Pascali made friends with Sandro Lodolo and shortly after he began to collaborate in his advertising studio, Lodolofilm. Over the course of ten years, he will make dozens of carousels. For Algida ice creams, in 1960, Pascali created "The Killers". However, the customer did not accept the proposal, deeming it unsuitable due to the too modern graphics for the time and the scenes of violence. However, Pascali continued to develop the subject by intervening on the style of the characters, creating sketches and sets and creating the basis for an independent animated film. In 1967 a trailer lasting 1'37” was made and proposed to the Cineriz production house, which appreciated the project but did not want to produce it because they considered it too sophisticated. Despite the second refusal, Pino Pascali continued to work on this project until the summer of 1968, when his life was cut short by a road accident.
