- The original ending is bleak and violent. After the movie did poorly in theaters, a new, happier ending was shot. This lighter version is the one that has been seen for decades. The Swiss Cinematheque has a print of the darker version, which has now been shown at The Museum of Modern Art in New York City. The 2015 restoration also uses the darker version.
- There is an Italian edition of this film on DVD re-edited in double version (1.33:1 and 1.78:1) with the contribution of film historian Riccardo Cusin. This version is also available for streaming on some platforms.
