Ok, I'm watching Andrei Rublev and I wonder. Are there other films like this? Are there other intelligent films involving people searching for answers to unanswerable questions? Questions about faith or humanity. I'd really like to see some movies that really make you question yourself and your existence.

Maybe you should check out White Chicks

EDIT: (For real) I'd suggest checking out the Seventh Seal by Bergman

Here are some that I liked from top of my head...

Nostalghia (1983)
2001: Space Odyssey (1968)
Stalker (1979)
The Wind Will Carry Us (1999)
Taste of Cherry (1997)
L'Humanite (1999)
8 1/2 (1963)
Enigma of Kaspar Hauser (1974)
Paris, Texas (1984)
Code Unknown (2000)
Lost Highway (1997)
Sweet Hereafter (1997)
Man on the Train (2002)
Contempt (1963)
Persona (1966)
Silence (1963)
Winter Light (1963)
Dreams (1990)

Waking Life

1984

Ordet
The Seventh Seal
Ikiru
The Sweet Hereafter
Stalker
Hiroshima Mon Amour
Bowling For Columbine

I'd recommend Kyslowski's The Decologue or Three Colors Trilogy.

The lost highway still confuses me now. But if you're looking for a movie with questions, then this is the movie to watch.

Chris Marker's 1982 Sans Soleil. A tour-de-force documentary (you don't have to like it) spanning from Japan to Iceland to America and back again that weaves intricate images about world culture and faith that just seeps into your subconscious.

Eternal Sunshine of the Spotless Mind

Nine replies, and nobody has mentioned Tarkovsky's The Sacrifice yet?

Thanks for all the choices everyone.

Check out Mindwalk with Sam Waterson, John Heard and Liv Ullmann.

Woman in the Dunes

The Sweet Hereafter is one of the most deeply moving films I have ever seen.

It's non-linear and requires (or I think it does) repeated viewings.

I did a report about it in a film class. I had already seen it 4 or 5 times, and then I watched it and wrote the paper in the middle of the night. I did well on that assignment.

It's about hope, love, loss, responsibility, drifting away from your grown children.

It's a masterpiece in the truest since of the word. I think everyone should see it.

I see several others have listed it above as well.

Atom Egoyian is the director, Sarah Polley, Ian Holm and Bruce Greenwood star.

BTW - don't watch if you've had a bad day.

Seems like they show this movie in every Philosophy class i've taken. Poor acting and stodgy, stiff script and writing, but great intellectual musings.

Dawn of the Dead!

No, I'd say movies like Pi...

I'll recommend Requiem For a Dream and A Clockwork Orange

Soul Plane!

Mulholland Drive
The Usual Suspects
JFK
Bowling for Columbine
Fahrenheit 9/11
Malcom X

Watch PBS or Discovery.

Gay******s from Outer Space

The title alone is mind boggling.

EDIT: for the curious - http://www.imdb.com/title/tt0274518/

House of games-great movie about the human condition

I second that, I saw it in my early teens and was totally fascinated by the conversations - I don't remember anything about the movie or performances, it was all about the writing.
