The band Gnarls Barkley sampled the soundtrack from this film for their hit song "Crazy".
Following the success of the Bud Spencer/Terence Hill Italo western comedies in Germany this film was re-released as a re-dubbed comedy version in the late 1970s. Therefore it was heavily cut to 82 minutes and changed in plot. Django (now renamed to Joe) even mentions "the big" a few times referring to several characters of Bud Spencer in other movies.
Django had his name changed into Trinita for the French version, but no attempt to turn the film into a comedy was ever made.
German Import DVD has a Super-8 Version (German language only), as a special feature on the disc.
