A mute, violent hero (the leader of an outlaw band) single-minded in taking vengeance (on the accomplices who have betrayed him)... Well, it looks as though the viewer is off for just another spaghetti western. And during the first undistinguished half, their fears ARE well-founded. But hope should not be given up, all is not lost. Indeed the man at the helm is none other than Antonio Margheriti (aka Anthony Dawson), a pleasant minor master particularly at ease in fantasy films ("Horror Castle", "Castle of Blood"). And when (rather unexpectedly to be true) the director suddenly remembers what he is really good at, the run-of-the-mill flick is metamorphosed into an unidentified (and inspired) cinematic object. "Vengeance" is still a western, complete with duels, showdown and Morricone-like score, but from then on it gets mixed with thriller (the delayed discovery of the traitor; the astonishing flashback unveiling the true facts about the bank robbery) and horror ((the long final sequence in the sulfur mine with its extravagant lightings and baroque framework ; the villain appearing as a grotesque clown). No longer apathetic, the viewer is now agape. The lesson to be drawn is that if you demand more of a film than just B (or Z) features, just have patience and you will be rewarded. Like Rocco, the hero of the story in a way...
