Extranjero, your thoughts about Django and Corbucci are quite interesting, but differ from mine in some aspects.
Yes, the saloon shoot-out is excellently filmed and edited, but the 3 big actions scenes are not, they are mostly disappointing for me, the editing is often lame, and the film suffers from that. Similar btw to FoD, in which Leone created this SW kind of quickly edited shootouts, but also fails to find a concept which make the larger action scenes work.
Leone did not really knew how to make them work, as later Giu la testa still showed, but Corbucci mastered this with his later editor Eugenio Alabiso, and especially Il mercenario and Companeros have a brilliance for these bigger action scenes, you donāt find in any other Spag.
It may sound insolent, but I wish I could re-edit the shoot-out with Jacksonās clan men, in which Django reveals the secret of his coffin, which is conceptually brilliant.
Red Pastures and Massacre at the Grand Canyon are 2 English titles for the same film, and Corbucci himself said he shot only a few scenes as hired hand for that one, and actually the film does not look for a second like a Corbucci western, but we donāt know for sure.
Django was indeed a big, big step forwards for Corbucci, but the 2 Spags he made before Django show that he had already the potential.
Here my views differ completely.
The Hellbenders is a forgettable film for me, and I think Django could have become a perfect film if made later in his career, if he had filmed this screenplay in 1967 or 1968, with a slightly bigger budget, with the experience he garnered especially with Navajo Joe, another āhired hand Spagā.
The Great Silence benefits from this experience, and is therefore for me clearly superior to Django, which is for me the flawed one of these 2, and Il mercenario was then a bold step in a different direction.
You think Il mercenario is shallow, I think it is a complex film, even his best (but with The Great Silence being on the same level), one which showed to what genre innnovations the SW was able.
In his 3 best westerns (and Django is of course one of them) Corbucci did things which were ahead of its time, alas he then stopped soon making good films at all, and after the partly brilliantly filmed Companeros, he lost by an by even any of the skills he had developed in the second half of the 60s.
