Pi, Requiem and Donnie Darko were great. Dancer in the Dark is a bit different from the others though. It is very odd yes, but not quite in the same vein as the rest. I knew nothing about DITD when I bought it, but I've always liked Sugarcubes / Bjork so I bought it blind. I LOVE the music in...
I think it would be a good flic even if it had unknown actors in it. Aronofski is a great director and has a knack for being able to really bring out and convey the emotional state of the characters. Looking forward to it.
