Lux Æterna from Requiem For A Dream. This piece of music is every bit as incredibly disturbing and gut-wrenching as the film itself. It is so beautifully crafted I can't stop listening to it. Alfred Hitchcock managed to associate violin with gore, and Darren Aronofsky - or more precisely Clint Mansell and The Kronos Quartet - took that to another level in that they produced hauntingly beautiful music that stays with you and not just annoying high-pitched violin noises that make you grit your teeth.
I love Requiem For A Dream. I read that Aronofsky wanted Giovanni Ribisi in the role of Harry, which would have been awesome as I'm a big fan of Giovanni and can totally see him killing it as a heroin junkie. Jared Leto was fine though, although in the beginning I had quite a hard time believing he was an addict due to his clean-cut image. Jennifer Connelly is superb. I first saw her in In The Bedroom (a shitty movie, but Jennifer was great in it) and then in A Beautiful Mind (she did Requiem first but I saw A Beautiful Mind first so yeah.. and who cares about chronology anyway) and I thought her mind-blowing. There's something about her that says disconnection, as in she seems distant in her roles, but at the same time she's very relatable and real. Am I making any sense? Okay let's put it this way. Zooey Deschanel is also distant and disconnected (and hot!) in 500 Days Of Summer, but in a more flaky and stoic way, while Jennifer is more emotive and expressive but still somewhat spacey and out of reach.
But the show stopper in the movie must be Ellen Burstyn as Sara Goldfarb. Her portrayal as a lonely woman addicted to prescription pills is just pure genius. She brings this frightening bipolar quality to the character the way Meryl Streep did in Sophie's Choice. And Streep went on to win an Oscar for that (just sayin'). Sara Goldfarb's monologue about being old and ignored makes me cringe. It's so true on so many levels that I wouldn't want anyone past 40 years old to see this movie lest they'll end up being junkies.
All in all, I've watched Requiem many times and each time, I got goosebumps. Hats off to Darren Aronosfky, and I can't wait to watch Black Swan (also by him, plus there's Natalie Portman and Mila Kunis totally doing it).
