The character of the restaurateur's daughter is played by Stefania Castellari, the director's own daughter.
The shoot-out at the train yard was filmed over the course of four days.
Director Enzo G. Castellari said that while he usually shoots his films in English, he shot this one in Italian, to be dubbed into English later, because lip-synching in English was too difficult for star Fabio Testi, who spoke no English at all. Castellari also said that he was quite dissatisfied with the English dubbing that was done.
Even though American actor Vincent Gardenia spoke Italian fluently, all of his lines in the film - which was shot in Italian - were dubbed by an Italian actor.
