If you’re into movies then you should be on the Raindance mailing list. You should like their Facebook Page and you should follow them on Twitter.
Every now and then they come along with gems like these. Until tomorrow they are offering scripts and production notes from Christopher Nolan for download on their site.
You can read the scripts for Momento, Inception, Batman Begins and The Dark Knight amongst others as well as some analysis and production notes.
Grab them while you can!
