A personal favourite. This is a long movie and I took a hip flask in when I went to see this on a date at Notting Hill's Electric Cinema back in the day. That worked wonderfully as this is a meandering film, probably best seen under some sort of influence.
Chicago Reader review:
Jacques Rivette's 193-minute comic feminist extravaganza is as scary and unsettling in its narrative high jinks as it is exhilarating in its uninhibited slapstick (1974). Its slow, sensual beginning stages a meeting between a librarian (Dominique Labourier) and a nightclub magician (Juliet Berto). Eventually, a plot within a plot magically takes shape—a somewhat sexist Victorian melodrama with Bulle Ogier, Marie-France Pisier, Barbet Schroeder (the film's producer), and a little girl—as each character, on successive days, visits an old dark house and the same events take place. The elaborate Hitchcockian doublings are so beautifully worked out that this movie steadily grows in resonance and power. The four main actresses scripted their own dialogue with Eduardo de Gregorio and Rivette, and the film derives many of its euphoric effects from a wholesale ransacking of the cinema of pleasure (cartoons, musicals, thrillers, and serials).
Here (and above) is the trailer.
