That's it, really. This is the best, or, at a pinch, one of the five best westerns ever made. And, despite being a kind of remake of the Kurasawa film, I think it's better than his movie, at least for westerners. Okay, he has Toshiro Mifune, but the Sturges film has McQueen, Brynner, Bronson, Coburn, Vaughn... as well as Buchholz and The Guy Whom Frank Sinatra Owed A Favour (Brad Dexter). Plus, the totally legendary Eli Wallech, in a wonderful turn as the villain Calvera. A lesser actor would just sneer and be, you know, evil, but Wallech gives him a twisted humanity. Like all the best villains, he thinks he's right. It's also interesting to see it as a sort of prequal to the work he does as Tuco, in The Good, The Bad, The Ugly; another one of that top five I mentioned earlier.
I just love this movie. When Brynner steps up and says, "Oh hell, if that's all that's holding things up, I'll drive the rig", I start grinning, and I don't stop 'till he and McQueen ride away from the village at the end of the movie.
