First of all, 2 glaring corrections:
1. 'Liquid Sky' is NOT an Aussie movie...it's an American film.
2. 'Liquid Sky' was released two years before NOTC, and has no thematic resemblance to the NOTC. I think the poster below me is thinking of a different movie, about a man who wakes up in Sydney to find himself seemingly the last man alive. Can't remember the name of it though.
Don't believe anyone who tells you NOTC is a disgrace...it isn't, it wasn't meant to be the uberartistic art-fag opus that many people for some reason seem to think everything should be. It's simply a cheesy 80's movie that centers around 2 valley girl sisters who decide shopping and listening to Cindy Lauper tunes will cheer them up after a comet turns the majority of the population into red ferrous-oxide dust, and turns most everyone left who isn't immune into flesh-hungry zombies...and any movie with zombies ain't completely bad. Face it people, we need more zombie movies, and this one's a toot. Not perfect by any means, but I'm proud to have it in my collection.
