Lady in the Water
Shyamalan, who credits the development of the movie to a bedtime story he told his children about what happens in their pool at night, wrote the 72-page children's book "Lady in the Water: A Bedtime Story" (Little, Brown, New York, ) to coincide with the movie. The book was illustrated by Crash McCreery and released the same day as the film, July 21, 2006.
