Depending on your point of view, you may find this quite interesting (gosh, I get to read a bunch of good screenplays for free. Whoo hoo!) or depressing (I have to compete with how many screenplays for my Dark and Stormy Zombie Prom Night script?). IO9 had this short post on how to read the top 250 unproduced Hollywood screenplays for free.

Here is a brief synopsis of the screenplays from a 2008 post in the SlashFilm blog about scripts under consideration, referred to as the black list, which has an earlier perspective. You'll notice that a few of them were or are in the theater this year. I don't know if this list exactly matches the list of readable screenplays below, but there should be a large overlap.

Here is a collection of PDF files of the 2008 screenplays.
