About the movie Vanilla Sky.
It has this obsession/delusion/illusion/paranoia thing about a guy frequently mistaking two women whom he is emotionally/sexually attracted to, Sofia (Penélope Cruz) which he truly likes, and Julie (Cameron Diaz) which was like a sex thing, and she ends up stalking him, and drives them both off of the bridge in a car at a high speed, supposedly killing herself and drastically disfiguring him.
The illusions come from a lucid dream hibernation program, which he enrolls in, in order to be restored by better medicine in a near future.
But Julie is also aware of the program. In the end, he wakes up in the future - no money left, but supposedly already repaired - and a voice says: "relax David, open your eyes", or "open your eyes David, you are going to be fine" in the alternative ending. The movie ends with no further explanation (which is actually very cool).
The voices from Julie and Sofia are quite similar, and they are both great actresses, and I couldn't distinguish from whom it is (I do believe that the alternative version is Sofia, but not in the 2001 version).
Is it Sofia who waited for him, but the movie hints that she had move on to another guy, and then he's all happy in a bright future?
Or is it Julie, who might have enrolled the hibernation program - as she was aware of it in a hinting scene - and deliberately crashed the car, and waited decades also on hibernation only to stalk him again in the future, and thus make his like miserable for a long, long time?
