10 movies that shock and awe

"Requiem for a Dream" (2000)

Tagline: From the director of [Pi]
[Note: This is only (somewhat) shocking if you've seen "Pi."]

Director: Darren Aronofsky

The plot: Four people experience the ravaging effects of drug addiction. Whether it’s aging widow Sara Goldfarb (Oscar nominated Ellen Burstyn) binging on diet pills or her son's beautiful girlfriend Marion (should've been Oscar nominated Jennifer Connelly) prostituting herself for a fix, "Requiem" is a riveting and sobering look at drug use.

The shock: Amputation, shock therapy, a stomach-churning Upper Westside sex party.
