Stardust Memories is my favourite. It's basically a full-on homage to 8 1/2. Very much a precurser to Deconstructing Harry (which I also love). It's something of a filmed mental breakdown (as is 8 1/2) about a movie director who used to make comedies and now wants to make more serious movies, but the public keeps wanting his "early, funny ones". (Sound familiar?)
It's fascinating the amount of self-loving and self-loathing one man can have and put on screen (maybe Vincent Gallo will make his 8 1/2 one day...!). I've said earlier in the thread how ridiculous and funny I find his claim that his movies are not about him: you just need to look at this one. He's directly making reference to the fact that he recently made Interiors and it was critically mauled (undeservedly). The film opens as if it's a symbolic, deep opening (a la Fellini, or possibly Bergman), only for the beginning of the movie to be shouted down and ridiculued by studio executives claiming, "I've seen it a thousand times: artists trying to justify their own petty neurosis by attatching them to these adolescent philisophical themes." "Why doesn't he just stick to making people laugh?"
It really is a beautiful thing. Charlotte Rampling is astounding as the mentally unstable girlfriend, as if she walked right off the set of one of Bergman's best female character studies. The movie has a particular kind of transcendental, surrealist visual beauty that I feel none of his others have (the images of Woody as a child magician, flying, being given an elephant). The conclusion is just wonderful, and moving and true - then the audience watching the movie walk out telling you it's wonderful and moving and true...
I guess basically I'm just a sucker for the whole tell-it-all-in-art thing, and this movie really is the epitome of his career if you want to indulge that particular fetish.
