Reading screenplays before or after viewing a film can teach you a lot of about how a film changes and develops throughout production. It is also a lot of fun to find missing things and figuring out if you should blame the writer or director for particular scenes. One of the best sources for screenplays on the web is Drew’s Script-O-Rama.
Script-O-Rama is a collection of links to film, TV and anime scripts from across the web. The site is a direct path to hundreds of scripts. A lot of the films featured have multiple drafts and there are even completely unproduced screenplays (wanna read Michael Chabon’s Spiderman 2, or how about two different rejected Freddy vs Jason scripts? How do these stack up against the one the studio finally settled on?).
