Do you like gang movies? Thrillers?

If you want comedy, these are the best.
Airplane, Monty Python and the Holy Grail, and Hot Shots part deux

Attack The Block;
It's bout this gang in london who have to kill some aliens :P

Thanks for the suggestions everyone.
I've watched the start of Airplane! and got bored so I decided not to watch it. I'm impatient, yes, but next time I'll make sure I watch it all, hearing all the good things about it.

I'm not sure if I like gang movies, to be honest, I haven't watched a big variety of movies to say whether I like quite a lot of genres. I know I don't like horror, unless it's actually a clever film, that has a meaning to it, and makes sense, Not like some movie about zombies and such things.
Thrillers... Hmmm... Again, I don't know but as far as I know, I love thrillers.

Hmm..

The Butterfly Effect.
Inception.
Requiem For A Dream.
The Chaos Theory.

I recommend you watch The Chaos Theory first. It's a fantastic movie. Highly recommended.

I've already looked up the butterfly effect, and I'll watch it soon.
I'll watch all of them probably, the titles seem pretty good, and I've heard many great things about Inception.
Thanks.

You're quite welcome. I do enjoy good movies. These are some great ones.
Yeah, Inception is one of the few movies that has come out recently that has been very, very well done.

I completely forgot to mention my love for The Matrix Trilogy, I enjoyed them films so much,

Shutter island

I'll check it out. Thank you.
