Writing Dialogue for Scripts deals with the media of stage, radio, television and film, giving a great deal of practical advice. This revised and updated edition also includes a number of examples of the most recent scripted dialogue. Chapters deal with how conversation works, naturalistic and stylised dialogue, pace and variation, scripted narration, comic dialogue and presentation. As well as highlighting the ways in which dialogue varies from one medium to another, this book shows how many of the skills of writing dialogue may in fact be applied to all the script media.
Bit pedantic, but Davis knows his stuff. There's a lot of useful kernels to be gleaned from this trim tome. If one grows impatient, they can also skip ahead to chapter 12, Reworking the Dialogue.

I enjoyed this book, liked the fact that it was brief, that he uses dialogue from real plays, and found a reminder of many essential ideas in writing scripts.

Few producers stage Shakespeare's plays using the full script. Here's a quote: "The basic point is that conversational dialogue, unlike written dialogue, is a mess."
