3/ Close ups. Close ups of eyes and other body parts are common (best done on Charles Bronson at the end of OUTITW and at the beginning of FFODy). Often parodied but I believe only done with conviction by Leone are the close ups of things like boots and hands wavering by guns (accomponied by Ennios music)
Leone's movies are brilliantly absurd and that is what elevates them over other Western that was ever made.
Maybe not really present in the dollars-trilogy, there's much melancholy his later films. It's always something that makes me identify with his films. He must have been a very melancholic and nostalgic guy.
That was something I also thought. OUATITW, DYS, and OUTIA were so depressive, that I wondered: My! This guy must be totally depressive, he must be alway sad! How can he had lived his life? It's a paradox, but no, Leone wasn't like his later movies. In life he enjoyed laughing, discussing, eating, to be with his family. He considered himself as lucky to have this sucess. I read that in Ray Freakling book. When I read the book I searched if Leone have had dark moments in his life, but I didn't really found them. He was simply critic toward History and about political engament. He didn't believed in politic because of the fascism and the fact that his father had to give up his career as an actor because he was a communist. But no, Leone's life wasn't under the sign of sadness, this feeling is simply extrapolated in his films. But the guy in itself had a Roman temperament, a dynamism, wich was all the contrary.
