Oh cool, a Sci-fi top 10.
1) Empire Strikes Back - My favourite ever film.
2) Aliens - Let's Rock!
3) The Day the Earth Caught Fire - Peter Stenning, my hero.
4) Star Wars - Once Han Solo turns up, it's a riot.
5) Forbidden Planet - It looks so good, even now.
6) The Matrix - The first film is superb, the others, well..
7) Star Trek: The Motion Picture - Criminally disregarded, perhaps...
8) Escape from New York/The Thing - Carpenter+Russell = Perfection.
9) Andromeda Strain - I just love the quiet menace and split screen filming.
10) Logan's Run - Not only do I love the guns with green muzzle flashes, but I also love Jenny too.
I suppose 2001 should be in here somewhere, but it's a bit hard going in places... I actually prefer 2010.
