Django, Prepare a Coffin(1968)

Synopsis

A mysterious gunfighter named Django is employed by a local crooked political boss as a hangman to execute innocent locals framed by the boss, who wants their land. What the boss doesn't know is that Django isn't hanging the men at all, just making it look like he is, and using the men he saves from the gallows to build up his own "gang" in order to take revenge on the boss, who, with Django's former best friend, caused the death of his wife years before.
