Dogs In Space, an Australian film from 1986. Among the cast is Michael.Hutchence, former lead singer of INXS.

It's about a bunch of young people sharing a house in the suburbs of Melbourne. It has no real story, although from memory it culminates in a big house party scene. It's shot in a pretty unique way where the camera just wanders throughout the house and there are constantly things happening. Conversations sort of start and stop abruptly as the camera wanders around so you have to piece together the different snippets to develop an idea of who these different people are. Watching it sometimes feels like you're a silent housemate of these people, just observing their chaotic lives.
