This movie, by the same director as Pi and Requiem For A Dream, was just released on DVD last week. It's a fascinating exploration of topics such as multiple realities, death and rebirth and Mayan cosmology. It's not very linear, and it would be difficult for me to say exactly what it all means, but watching it is a kind of trip (it has a kind of psychedelic visual style) that opens your mind and senses to archetypes such as the Tree of Life. I still have to watch some of the commentary that is included on the DVD. In a way, it deals with similar concepts as the more popular What The Bleep, but in a way that is more artistic and open-ended, and therefore less accessible to a wide audience. Anyway, it's worth checking out if you like mystical films.
