Name 1 one movie everyone should watch, pick 1 movie mentioned in this thread and watch it

The Salt of the Earth.

Recommending all of these because I just can't pick one:
Multiplicity and Earth Girls Are Easy if you love funny older movies (cca 80s)
Abraham Lincoln Vampire Hunter - surprisingly fun O.o
Brotherhood of The Wolf - totally cool, has a sexy native American, what more do you need?
Dogma -my mom's fav movie besides The Fifth Element, must have seen both of them over 100 times xD
K-Pax
Interview With the Vampire
Little Nicky
Legally Blonde and Legally Blonde 2: Red, White & Blonde
the very sexy Riddick -because come on, it's Vin Diesel with the "it's an animal thing" and you can't say that's not yummy <3
Taken and The Grey - because both movies are really good and especially because... Liam Neeson is a DILF <3
Soldier - great story
any Indiana Jones (except for the last one xD) - can't say no to Indy. Except for the last one... Come on, Nazis, aliens and a long lost son? Desparate much? xD
anything with Marilyn Monroe in it (especially Gentlemen prefer blondes ) - because.. Marilyn <3

Gonna watch The Princess Bride.

Hot Fuzz or cornetto trilogy in general

Has Eurotrip been mentioned alrdy? ;p

AntiChrist.

Shits creepy as fuck.

Cecil B Demented
Idiocracy
Hitchers guide to the galaxy
Ice pirates
Revenge of the Nerds

Escape from New York would be my suggestion. The sequel is Escape from L.A. if you like it. (:

I was gonna recommend fight club. That movie was incredible. Didn't really know what to expect when going into it and I loved it all the way through!
But i'll recommend "Now you see me".
I think i'm gonna watch usual suspects as well since I already have that downloaded.

The Man From Nowhere, revenge flick with heart

Le Illusioniste. Massive trigger warning, by the way. Don't watch it if you're the least bit down. I was in a good mood when I started, and couldn't sleep that night because of how depressing it was.

No one has said Plague Dogs? Shame on you people!

Pan's Labyrinth

the pianist, when I first watched it I couldn't believe I've not seen this movie before + it's based on a true story!

I'm so tempted to write

Human Centipede

At this point i guess everyone said most of the classics i am just gonna list a few anywhere

Citizen kane
Big trouble in little china
THEY LIVE
Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb
when i get to my house in a day or two i will edit this and add more that i cant remember right now

Also a couple ones that i have heard that are a must watch but havent seen yet

Soylent Green
5 millions years to earth

I have seen 90% of the mentioned movies.. and 1 particular movie that I haven't seen and I should of watched and planned to watch a long time ago is Groundhog Day. Gonna watch it tonight

Go watch

District 9
Its about alien vs human... no no, aliens are not invading earth.. but they are invading earth... not literally. They are overpopulating earth and humans are getting annoyed.

OXV: The manual. Or you can find it by "Frequencies". Just watch it, it's amazing.
Your mind is going to explode

Goodfellas for its great story and soundtrack
The departed for its story
Godfather because Godfather
Forrest gump because it was a great overall movie

Hot Fuzz

Alien(s)
Seven Samurai

Bourne Trilogy, good spy action.

I was going to suggest Seven Samurai, but someone else already has. High Noon another movie that everyone should watch. An old movie, but a deep one, this film is a microcosm of everything going on today. Times may change, but people are still people.
