Rewatched this one today.
I guess I'm watching a lot of US westerns made in Spain lately. And a pretty mighty film this one came out, very good, well filmed, a good and not absurd story, based vaguely in true events, Pancho Villa did lead the last foreign incursion to US home soil, in response General Pershing commanded a raid to capture Villa in Mexico but failed, he would later become the commander of US troops in France during WWI, but like I was saying the film is pretty violent, but nice to follow, more US western than spag, perhaps with a more "Italian" score it may have looked a bit more spaghetti, but its a US western all right, also the production values are very good Hollywood style and that makes a difference, they didn't shoot the film just in Almeria they filmed all over Spain.
So the film does have a very professional look if I may put it that way, also I like Peppard, he wasn't the best actor around, but he was quite a unique character and had is own charisma and he brings it to the film.
So a very well action packed western, easy to follow, I really don't really need more to like this one, which makes it above average to me.
