What is your favorite movie of all time ?

Ex Machina and Mad Max: Fury Road are probably my favs. Also Guillermo del Toro's movies usually end up being high on my list.

Inception

Blade Runner.

The Green Mile

Citizen Kane

OH also NACHOS LIBRE
Classic jack black!

Do watch
Иди и смотри/Come and See (1985)

Well I guess if I had to pick just one I'd have to go with a somewhat "boring" one and pick The Godfather.
Boring, as in it is pretty widely considered to be one of the best movies of all time, but that is for a good reason.
I wouldn't say I was very interested in the premise when I first saw it, but the movie is just so well made, the brilliance is undeniable.
All the elements just work together seamlessly and makes for a truly magnificent piece of art.

Edit: Oh yeah and OP, I think it's quite a stretch for some of those movies to be on your list of movies people "probably" haven't seen.
I mean at least as a person who is a bit of a movie buff, I've seen most of those, and if a person has seen any anime, they've probably seen Spirited Away :D.
But yeah I guess most of those can still be considered movies people probably haven't seen, if they're not that into movies.
Into The Wild and Zodiac are probably in my top20 movies of all time and both are at least in my top10 movies of the past 15 years.
Funnily enough, I've actually rewatched a lot of those movies (The Exam, Zodiac, Stranger Than Fiction, Mr. Nobody) in the past year or so and I don't even watch that many movies these days, rewatch even less, so it's a pretty weird coincidence :D.

House II
not the best, but definitely the weirdest. Start watching a horror movie, go to make some popcorn, and it's an indiana jones type of adventure; go get a drink, and it's a frat comedy; bathroom break, and it's a western

into the wild

I'd say Blue Velvet is the one I rewatch the most. Carpenter's The Thing would be a close 2nd.

Training Day
&
The Professional(Leon)

Sen to Chihiro no kamikakushi
Gladiator
The Godfather
Léon
The Silence of the Lambs
The Prestige
A Beautiful Mind

Heat (1995)

My favorite movie. Hummm. I guess it would be Alien, and Aliens.

Just use Imdb. You can always find something interesting there! Just choose one from Top 250 :)

Jurassic Park now and forever.

I'd have to go with Bladerunner. :X

Oh man
Probably between Mr.Nobody and Frequencies for Romance type
Tron Legacy, Pacific Rim, Death Race, and Hardcore Henry for Action type
Momento, Fight Club, and Shutter Island for WTF kind
And many more. Please don't make me choose ._.

One awesome movie that not a lot of people have seen is

Millenium Actress
http://www.imdb.com/title/tt0291350/

Maybe because of prejudices. Don't miss this masterpiece.

I actually have seen Into The Wild! :D
We watched it at school, haha. Didn't think it was that great though.
I also know Spirited Away.

My favourite though? I'm not so sure. I stopped watching movies a few years ago.
Do parodies count? If so, I love the parodies a German YouTuber made of the Harry Potter films (she just re-dubbed them and now I just can't take the films serious anymore).

Sin city !

U Turn (1997)

They Live
