I have recently been going through the list of Film 4's 'Films to see before you die' (http://www.channel4.com/film/reviews/feature.jsp?id=161521). While I have found some to be okay I have come across one called 'Brazil' which is absolutely fantastic and has instantly become one of my favourite films. It is written and directed by Terry Gilliam (Tom Stoppard also co wrote the script) and if your familiar with Gilliam's work you'll know what to expect from this film.
It stars a young Jonathan Pryce (aka the villain from the Bond film Tomorrow Never Dies) as a lowly administration worker in a world obsessed with filling out forms for anything and everything. He tries to correct an admin error but instead ends up being accused of being a terrorist.
It has a great cast with some really brilliant cameos from the likes of Bob Hoskins and Robert De Niro. The sound track fits so well, you might even recognise the main theme which a little rubbish clearing robot called Wall-E has used recently.
I don't want to say too much more because I watched the film knowing nothing about it which I find is usually the best thing to do with films and I just don't want to spoil it.
Anyway I would probably advise you not to watch the trailer I'm adding below but I know some people like to see trailers before they can get interested in seeing a film so I've added it anyway. So if you can hold off from watching the trailer then that's great, but whatever you do go and see this film. It's probably not to everyones taste but it's definitely worth watching anyway.
Go watch and enjoy.
