It is quite known today that Shelley Duvall was emotionally damaged because of her role in The Shining, especially after Dr. Phil exploited her mental illness on TV. While the finished product seemed very authentic, Shelley Duvall was often mistreated on the set. Kubrick was extremely critical of her acting. You can even see a glimpse of this in Vivian Kubrick’s documentary of the movie when Kubrick told Duvall’s co-workers to not sympathize with her. It certainly made Wendy Torrance seem like an insecure woman who was fearful of her husband, but it was at the cost of Duvall’s mental health.
