I just saw
The Fountain by Darren Aronofsky and my head is literally bubbling over with thoughts about the movie.
Actually I saw it yesterday the first time and now I have rewatched it with Aronovsky's audio commentary (funny part: Warner Brothers didn't want an audio commentary on the dvd, so he made one as a mp3 that you can download. It's a pain in the ass to sinc the dvd and the mp3, but it's worth it) Regarding the central themes of the movie, it has brought forth more questions than answers though, so I will share my interpretation of the movie.
Everybody who has seen the film, I'd really want to hear your interpretation, everybody who has't, go rent it and then join the discussion ;-)
So my interpretation:
The story of the Conquistador is the plot of the book that Izzy is working on, straight up to the fight of Thomas with the Mayan priest.
The story in the now is real, as is the story in the future (the bubble/spaceship). The tree in the future is the tree which Tommy planted on Izzi's from a seed which he found in South America (the same tree of which he used a sample on the monkey). So his eating of the bark of the tree makes him immortal (long enough to reach the star). When he reaches the star as the star explodes he has come to terms with his own death and the death of Izzi and he is allowed to reshape the way in which he handles Izzi's dying (he runs after her instead of going to operate on the monkey, so he accepts her death instead of trying to fight it).
The last part of the story of the Conquistador leaves me unclear. I'd say that it is his writing the last chaptor of Izzi's book, but there are two things that don't fit for me. First, why does FutureTom appear (as a floating figure) in the story and second, how does the ring that the Conquistador lets fall down appear in FutureTom's hand?
Questions over questions, and I'd be really interested to hear your answers.
