Dio perdona... Io no!

Peter Martell was cast as Cat Stevens but broke his foot at the beginning of the shooting and was replaced by Terence Hill, who met Bud Spencer for the first time.

Kid plays with a plastic ball at the beginning of the movie.

This film was released in three different versions in Germany. First in 1968 the original theatrical release which had a "Not under 18" rating and ran 95 minutes (ca. 12 minutes were cut). This version was released in 2001 on home video by Screenpower (re-rated "Not under 16"). In the 80s, due to the popularity of the Spencer/Hill comedies, the film was re-released by Tobis in a spaghetti-western-like "comedy version" (this version was re-dubbed and missed about an additional 14 minutes) with a "Not under 12" rating. It was often shown on TV and released on home video by various companies. In 2003 the original uncut version of the film was released, again by Screenpower (also with a "Not under 16" rating).
