While we're on it then. People's top 10 films of all time. I'll start off.
1. The Big Lebowski
2. The Matrix
3. The Usual Suspects
4. The Shawshank Rdemption
5. Almost Famous
6. Pulp Fiction
7. High Fidelity
8. Good Will Hunting
9. Toy Story
10. Groundhog Day
Stuff like Dumb & Dumber and Goodfellas are unlucky to just miss out there. Plus mentions to Planet Of The Apes (1968), 12 Angry Men, All About Your Mother, Die Hard, Leon, Trainspotting, The Truman Show, LOTR: FOTR.
That's probably my top 20 there. Bound to be a few I've forgotten too.
Edit - yep. Back To The Future, Fargo, Terminator 2, The Thing, Snatch, Amelie, The Diving Bell & The Butterfly, Ratatouille, A Simple Plan.
I really loved 21 Grams when I watched it too but I've never got round to watching that one again for some reason.
