David Morris (English) is the author of The Evil Hours, which director Debra Granik said was an inspiration for her critically-acclaimed feature film, Leave No Trace. She said, "I gave (actor) Ben (Foster) a huge file of articles. A beautiful book he and I found was also very meaningful. It was called The Evil Hours by David J. Morris, and it’s one of the most complete and exquisite accounts of a Marine who was able to chronicle his post traumatic stress...A book like that gives a director and an actor so much rich content."
