from wikipedia: Duvall has lived out of public view since her retirement in 2002. In November 2016, USA Today reported that she appeared to be suffering from mental illness.[29] A segment featuring Duvall on Dr. Phil in 2016 drew significant criticism from the public, with many suggesting that Duvall's mental illness was being exploited.[30] In the segment, Duvall refused offered treatment.[30]
I agree Another excellent actress for the part in the Shining would've been Veronica Cartwright. She was a horrific nervous wreck of scared emotions in movies Alien and Invasion of the Body Snatchers.
When she arrived at the set of the movie Alien (1979) Veronica Cartwright thought she was going to be the lead actress right up until the moment Sigourney Weaver showed up, and even then Sigourney Weaver almost lost the lead role because they thought she was allergic to Jonesy the cat (or I should say cats since I believe there were six of them) turns out it was the makeup she was using - and the rest is history.
Never heard of her. But I know she's in the Shining with those God awful shreeks and screams lol. DAAAANNNNNNYYYYYYY
