A film co-scripted by Franco Solinas. Solinas ends the film exactly as he ended Pontecorvo's "Queimada" (Burn!). Great performances by Lou Castel (a Colombian-Italian-Swedish actor), Gian Maria Volonte and Klaus Kinski. Kinski plays a decent villain for a change, wearing a cross and a priest's cassock! A film that launched Lou Castel's career. Morricone contributed to the music-credited among the film's credits.
