The character name "Sparafucile" comes from the professional assassin in Verdi's opera "Rigoletto," and the song Sparafucile sings is also from "Rigoletto": "Caro nome" ("Dearest name"), sung by the heroine Gilda, whom Sparafucile kills at the end of the opera.
The movie was considered so bad that it was re-edited and later released under the titles "Bowanga Bowanga" and "Untamed Women".
Shot in 1947, but not released until 1951.
