I saw this film at university in the eighties, and went out the following night to watch it again. I've been looking out for it on DVD for years now.
It is not a film where much happens, survivors trek across a post apocalyptic landscape, the film camera runs out of film and the cast and crew do nothing much, the director goes to Los Angeles to try and get the money to finish the film.
But it is not a bleak film, the characters are irritating but engaging and likable, they say interesting things, the film muses on the nature of stories and film-making. Particularly on the big screen, this is a really really beautiful black and white film, images are wonderfully composed. The camera lingers. Every shot takes twice as long as it might, but it is about looking and thinking.
This is a film with a tremendous sense of place, remarkable locations that dominate the passive characters.
