I really enjoyed this one:

"The 101 Habits Of Highly Successful Screenwriters: Insider's Secrets from Hollywood's Top Writers" by Karl Iglesias

Lots of useful information and quotes covering a range of topics, and arranged quite well.

Cameron Crowe interviews his idol (and, really, everyone's), Billy Wilder
