Another to look for is MEXICAN HORROR CINEMA by Rogelio Agrasanchez, Jr. It is very well done with gorgeous color of many of the Mexican Horror films. Highly recomended but it may be OOP by now.

Yes, I picked this up when it was first published, from Agrasanchez's website.  It's a nice softcover, coffee table book, with lots of full color poster reproductions and b&w stills (English text, too).  It covers Santo, mexican horror/sci-fi, vampires, monsters, etc.  A real treasure.
