This film is also known as Sundance and the Kid in the U.S. release. Starting as early as the 1970's most Euro-Westerns started going downhill in quality and budget. So Italian producers started combining the usually dramatic Spaghetti Westerns with comedy and later in 1970's with martial arts! This film, Sundance and the Kid, is just plain awful in everything from the acting to the screenplay. This turkey was cranked out to compete with the more original Spaghetti Western comedies with Italian actors Bud Spencer and Terence Hill such as Boot Hill, They Call Me Trinity, Trinity is Still My Name..etc. and also perhaps to certain extent the quality U.S. film Butch Cassidy and the Sundance Kid with Robert Redford and Paul Newman which is recommended if you want to see a quality made comedy-western.
Ironically, in my opinion, Italian directors made the very best westerns and the very worst westerns. On most all these Spaghetti Western-Comedies everything from the title of the movie to the names of the Italian actors, directors and sometimes even the production crew would change their names to American names and add awful English dubbing all designed to sound more American so it would sell better. In Spaghetti Westerns everything in fact is made in Italy but to make $$$ they had to make it look like an American made western as much as possible...but sometimes failed miserably as in this movie.
