Query: Underground classic

This is a complex, slow, mesmerizing film. Brando gives on of his best performances (see also Streetcar Named Desire, On the Waterfront, The Godfather and Apocalypse Now). Without Brando this film would have been utterly boring. It's the kind of film you have to watch a few times in order to make sense of everything. The film just starts and you have to put the pieces together--and character motivation is rather difficult to figure out. In fact, although this film is a good film, it's confusing as to why the characters do what they do. If you love Brando and Bertolucci, I'd recommend seeing this film. If you want to learn technique and style of acting--this is a very good film. I don't think we'll see another actor like Brando who gives memorable performances such as he does in this film.
