Following the scottish principles, I bought the DVD, I rewatched the film.
At least the film was better than I remembered it. It's still too naive and simple (but not too simple) to be a greater pleasure, but it was now somehow entertaining in an easy way and the directing seemed more assured to me.
The use of the here often beautiful looking italian landscape was quite good, even if the pass at the end was only a hillock and some of the scenes came back to the gravel pit grandeur. Only some of the action scenes are still terrible, as they look like childs playing cowboys and indians. But at the end we even got a short Leone like duel which was well enough staged.
PLL looked not as boyish as usual, and was generally good enough, even if in some scenes his limits as actor became again visible. And Nello Pazafini had a good time as Butch of Arkansas, the leader of the rebels who turns from a hero to a fallen angel.
The film was shot and released in 67 but actually looks more like one of the early Spags of 65.
