Cruelty. The emotions and thoughts inside a human being before they act out a cruel act of violence.
As I am knee deep in preparations for directing William Peter Blatty's LEGION, I am researching, reading and watching everything Blatty related, and came across this scene from The Ninth Configuration. http://www.youtube.com/watch?v=3VDYaS6Lpvk&feature=player_embedded Stacy Keach is wonderfully terrifying in this scene! This scene is just another confirmation to me about why Blatty is such a fascinating story teller. The worlds he chooses to explore are amazing to me.
