Good movie recommendations?

[R4L]

Of Mice and Men is a good watch. A Time to Kill is an excellent movie.

I agree with lots already mentioned (Memento, Pan's Labyrinth, Amélie, Fight Club, Twelve Monkeys...).
A few to add...
Children of Men - really interesting look at a world descending into chaos. Has some great single-take scenes in it.
City of God - gang life in the favelas of Brazil, based on a true story.
Sin City - brilliant visuals and gritty storyline. Rather gory, but if you can stomach that its definitely worth watching.
Airplane - well, you did say "extremely funny" movies...
A Chinese Martials Arts Film Of Some Description - like Hero, House of Flying Daggers, something along those lines.
The Matrix - If you haven't watched it, you'd better have the mother of all excuses.
The Shawshank Redemption - Cinematic masterpiece
Se7en - Another great Fincher
Butch Cassidy and the Sundance Kid - Classic, yet rather different western. And it has that ending.

I'm going to stop now.

I couldn't not comment these
Airplane only if you can turn your brain of and watch the whole police squad in marathon enjoying it.
Hero and House of Flying Daggers are more like chinese art films than martial arts films. This doesn't mean they're not good, on the contrary.
And The Matrix, yeah well. Not really a good movie, but a cult one that should on the seen list. For the sequals, if you have not seen them, don't bother

"Forest Gump" has got both humour and serios stuff.
As for my personal opinion, I find "Memento" pretty good. It's also full of flasbacks.

EDIT: Oops, Memento's already mentioned. I guess, you really should watch it then.

Funny, I was going to mention that, too...
