Interesting Fact 13: The Shinning (I know how I spelled it)

In the filming of the Shining, Stanley Kubrik and friend William Friedkin purposely tormented actress Shelly Duval on set, and somewhat convinced the rest of the crew to follow along, to help Duval get into character of a tortured wife and mother.  As a result, Duval became sick and lost a lot of hair while filming.
