Funny…the first time I saw 2001 was for a film class one summer; I had read St John of the Cross’s “Dark Night of the Soul” the previous day and noticed some parallels. St John talks about the overburdened intellect’s sense of lostness and loneliness and directionlessness…the more he learns the more he feels unworthy next to the immensity of God…but then St John describes this hypothetical person going through a purifying bath of God’s love and finally “leaving the world and works of man behind” and falling down “as in a stupor” before God Himself, where he still feels small compared to God but not insignificant or unloved.
The film, meanwhile, concerns modern man’s existential journey into the loneliness of space, summoned by a mysterious extraterrestrial message he doesn’t understand but which he wants to follow anyway…when the astronaut attains the planet he is destined for, he first has to go through the psychedelic star gate that pulls him out of his senses…and at the end leaves him in some mysterious chamber far away from the technological trappings of his space ship, lying down “as in a stupor” before the Monolith thing. And then he is apparently transformed into a baby…given new life drifting among the Heavens…I think it’s a sort of cool Catholic-ish image.
Ok, it’s a stretch! Personally, I just like to think that Kubrick used the science fiction genre to tell an allegory for the quest for meaning…an allegory that ends with man’s confrontation with something beyond him, rather than with a glorification of human technology or with the discovery of an alien species that is his sociological equal.
Sorry to ramble…former film student, here.

I think it’s nice to see the Vatican’s list, which recognizes great films even if they don’t have explicit religious themes. As long as it’s not explicitly heterodox, I think any work of art (music, painting, film, literature) that awakens in man a sense of beauty can be spiritually uplifting…the Pope listens to Mozart every day, for instance, and not too many of Mozart’s music was explicitly religious.
