David Eng has a cache of award nominated feature scripts.

I’ve gathered together thirty-six of the scripts that have been released so far. Most of the top contenders are now online, including 127 Hours, Black Swan, Inception, The King’s Speech, The Social Network, The Town, Toy Story 3 and Winter’s Bone. Even a very detailed documentary script for Inside Job has been released. I’ll update this page as more become available.

If you’re looking for reading, he has generously assembled everything all in one place for you. Check it out.
