Ah, this explains why Stuart Davis wrote about The Fountain in his blog -- there's a video interview with him and Darren Aronofsky available talking about The Fountain and philosophy. Although it is on a pay site, and I hesitate to post this link because of that, the note does say that you can...
Positive review of The Fountain by Stuart Davis of Integral Naked's Stuart Davis Show. Actually it is more of a blog entry but nice to see people getting it.
