I think the comment on the SWDb under Trivia that LO ammazzò was “Edited into Porno erotico western” is not well founded and should be replaced, then. Seems to me it was a rumour initiated by Weisser. See posts 58 and 59.
Also, I suggest two other editings:
Maurizo Centini might or might not have had something to do with possible new scenes added to the 1979 re-release, even the writing. But he had nothing to do with the screenplay of the 1972 film. This is I think another weisserism, and he should be deleted from the credits.
Girolamo La Rosa should be reinstated as responsible for the cinematography. He is credited as Direttore della fotografia of the 1972 film. He is on the Italian posters. He also was credited with the cinematography of Una cuerda al amanecer, which was shot back to back with the Spanish parts of Lo ammazzò. He also was the cinematographer of Pannacciò’s / Petrini’s two previous films.
