Based on the series of comic books by Morris which first published in 1946, this 1971 animated feature follows an original plot, but incorporates many characters and elements from previously published albums. An adaptation of the movie itself was finally published as a Lucky Luke album in 1982. Further more, a live action version directed by and starring 'Terrence Hill (I)' was released theatrically in some European countries in 1991. This served as the pilot to a short lived live action TV series, which used Daisy Town as the backdrop for most of it's action.
In the Spanish dub the story is not narrated by the horse unlike the original french.
For the English dub, Rich Little voiced all of the characters, using celebrity impersonations (Gary Cooper for Lucky Luke, James Stewart for the narrator, Boris Karloff for the undertaker Mathias Bones, etc.)
