Found scriptologist.com while contemplating writing a screenplay this afternoon. The website has some good information about writing scripts, as well as some great links to movie scripts online.
I have a few screenplay ideas floating around in my head at any given time, but haven't had the time or energy to put them down lately. I'm too busy trying to get Cold Magics finished. It is nice to think about, though, and today at lunch I started doing a script outline just for fun. Maybe once this piece is done, I can take the time to write a screenplay.
I think writing a horror movie would be neat, don't you?
