This is nice new lavish book, much like last year's excellent The Making Of Star Wars, from the same author.

Especially of interest here are the copious notes on early drafts of the scripts for each Indy film, outlines, transcripts of story conferences, etc; that give a great inside look at just how these screenplays changed from their initial conception to the finished product. Each film gets a meaty look at how the script/story changed.

It's $30 retail but I got mine cheaper through amazon.com if anyone wants to check it out there.
