Screenplay, Screenwriter.

I had wanted to stay abreast (no, not the right one) of the timelines for submissions (hot) for Project Greenlight, but alas, it got away from me. The deadline for submission (hot) of screenplays ends February 29.

And while I'm not 100% certain that I could not crank out a screenplay in that amount of time (however awful it ended up), I frankly have no idea about things like format, pacing (meaning, how many pages == a 2-hour movie?), etc.

I'm fretting over my lack of knowledge about the format and packaging of a screenplay, simply because I've never done one before. That's where some of you may come in. I know of an app called Final Draft that takes care of the formatting and appears to be the near-ubiquitous way to write a screenplay or teleplay. What I don't have a clue about, as I said, is pacing something like that. Do any of you (Crash, I'm thinking of you) have any pointers to books or even better, copies of well-known screenplays that I might use as a guide (or rosetta stone, of sorts) to help get me into that kind of groove?

Mucho grassy-ass for any help you might be able to provide. (Next up, i'll be asking for Spanish pronunciation keys.)
