“Best”? How about my favorite? Contact .
La Jetee
That is always my stock answer for favorite movie.
The Shawshank Redemption followed by American Beauty.
Lots of good choices here (a few not bad ones too) but I’ll have to go with Casablanca, Citizen Kane, Godfather 1 & 2, Third Man, Chinatown. Interestingly, the good guy doesn’t really win at the end of any of these.
Depends entirely on the criteria for “good,” but I’ll say:
Out of Sight
I’d agree with a lot of these,but 3rd Man has always been a grind for me to get thru.Could be the euro location/technique.A lot of these have a,well,foreign/heavy feel to me,like they’re speaking the native language and I’m not picking up the dialogue.
One of my personal favories is ** Detour **.Something in that film connects with me,like reading an old pulp story when I was a kid.Could (and have thanks to TCM) watch this one on semimonthly basis.
The Bride of Chucky… seriously.
Four votes for Fight Club? WHAT’S THE FIRST RULE OF FIGHT CLUB?
I’ll mention Pulp Fiction now, since it’s flawless and sublime.
Koyaanisqatsi and For All Mankind. Of course, both of those are documentaries, in the non-documentary category, I’d have to say Orson Welles version of The Trial. One can’t help but watch that and wonder what Welles would have done if he’d have had a decent budget to make the film.
Same as the second rule. Remember the last rule of Fight Club? If this is your first night at Fight Club, you HAVE to fight! 
The Truman Show
I hope you mean the original Japanese version.
<Comic Book Guy> Worst. Film. Ever. </Comic Book Guy>
As for my film, it’ll have to be Night of the Creeps.
Waking Life, Fight Club, Clerks. Not in that order. Fight Club is probably the best, but I could (and have a tendancy to) think about Waking Life for hours. If you haven’t seen it yet, track it down and be redeemed, heathen.

You know, as much as I wanted to chime in with the other movie geeks on this one and praise the original Japanese version, I have to admit I liked the remake better. Just a little bit. The original seemed to leave more to the imagination, but the American version creeped me out more. They’re basically the same movie, anyway.
My $0.02.

APOCALYPSE NOW.
The original version, not the re-released “I’m a fucking washed-up hack so I’m re-editing my best film to remind people that I was once a genius” version.
Saw it at a young age and continously revisit it…they don’t make movies as engrossing, entertaining, and thought-provoking as this one anymore.
My fantasy: A DVD release of the original cut with ALL of the footage from the 6 hour version included as supplement, and the film presented in the original 2:35 ratio and not the bullshit cropped 2:00 ratio the current DVDs have.
Either
Blade Runner
or
Thin Red Line
The Outlaw Josey Wales, endevor to persevere.
