"anyone seen the sequel or read the book? definitely intrigued"
What, Robinson In Space or Rentaghost The Revenge? It's more of the same basically, personally I enjoyed the first one more because I recognise a lot more of the places and it felt a lot more personally related to me but if you like the first one you should definitely check the second. I haven't read the book, nor have I seen the other film he made in the late nineties or whenever it was.
I guess you've seen Sans Soleil but if not that's a very similar film.
I forgot to mention that I watched a good film called The Bedroom the other day. It's a Japanese film directed by a guy called Sato (I think) that is basically quite a dark study of loneliness and alienation. The story is based on this woman who attends a sex club where the women (it's not clear whether they are paid) go and take a drug that knocks them out leaving them to be manhandled and raped by perverts who presumably pay for the privilege. The photography in some of these scenes is amazing with these luminous colours glowing strongly in the sinister bare black room. Anyway, the woman that the film focuses on is married to a man who basically ignores her, and she has another lover who seems strangely distant. Possibly as some kind of attempt at actual contact she ceases taking the drug in the club and merely pretends to be asleep as the attendees grease her up and rub their gas masks on her body.
There is a load of stuff about cameras watching people and some stuff with the main character and her lover both filming each other and rubbing their camera lenses together as some kind of alienated sex thing I guess. Also some people start dying and it gets a bit confusing (she keeps climbing in the fridge) - possibly because of the drug which may have some hallucianatory properties and is implicated in the death of the lead's sister who is seen in the first scene naked and wrapped entirely in clingfilm after an apparent suicide. The ending is pretty neat in fact and adds up to making most of what has gone before make sense.
