Favorite Existential Movie?

[Elly]

I love Stranger Than Fiction because it's about living life to the fullest in the face of death. Another favorite of mine with the same theme is American Beauty.

Lonesome Jim & Unmade beds. I think it's good movies for young people who have questions in 20-23 years old.
But real exist movie Is Zerkalo (mirror) by Andrey Tarkowsky. For me, it's harder then any other
