...by everyone's favorite screenwriting guru Syd Field.

I just wanted to bring this book up because I think that it'd be absolutely perfect to help writers of a few scripts I've read recently.

It focuses mostly on what to do at the point where you have the first or second draft down, but there's something a little wrong and the screenplay just doesn't work as well as it should.  It's got sections on everything you can imagine under the three main groups of plot, structure, and character.

That's about all I can say, but I strongly recommend it.
