I feel that I've watched a few more films recently that could fit into this thread. As well as working my way through most of Alain Robbe-Grillet's bizarre back catalogue I've watched Black Moon, Singapore Sling, What Is It? and, perhaps weirdest of all, Wax or The Discovery of Television Amongst The Bees.
Black Moon is directed by Louis Malle and seems to be the story of a (possibly insane) girl reaching puberty and attempting to escape a (literal) battle of the sexes by driving her car off the road and entering a beautifully shot, dreamlike landscape filled with unicorns, suicidal sheepherds and a bizarre family consisting of a mad old lady and mute twins - one of whom breast feeds her mother. Loads of references to Alice in Wonderland make this film a good companion piece to Alice Ou La Dernier Fugue and this is even more dreamlike and peculiar - although maybe, at times, a little slow and repetitive. I must confess I lost concentration at times in the middle which was a shame as the start was so intriguing and instantly exciting.
Singapore Sling
A bizarre Greek film that is best described as being somewhere between a film noir (specifically Laura which I'm sure is deliberately referenced) and Sweet Movie - and possibly Misery. An injured detective searching for his lost love (called Laura) arrives at the house of an insane mother-daughter duo who are just in the process of burying their chauffeur. They promptly imprison the detective and subject him to bizarre sex games involving vomit and electric shocks and then the film then gets pretty confusing, moving about in time via flashbacks and the like as the detective's voice over is delivered in a noir style. The film becomes a battle for power as the victim tries to play both of the women against each other. Also there is a load of stuff about the father/husband who is missing and the peculiar sex games they used to play with him. All shot in a claustrophobic and grimy black and white this is a truly odd film.
