If you are interested in making horror films then a good book to read is:
Horror: The Film Reader (edited by Mark Jancovich). It's good to read as helps to understand what makes a good horror, though can be quite theoretical.

Video Production Handbook (Gerald Millerson)
http://www.amazon.com/Video-Producti.../dp/0240513215 I definitely recommend to have in your book collection. As someone else said earlier "shot by shot" is another of those must have books.

Cinematography: Theory and Practice (Blain Brown) is another good read.
