After more than a decade away from the spotlight, Shelley Duvall gave an interview to Dr. Phil on Friday in which the actress reveals she's suffering from mental illness and claims that there are entities that intend to harm her.
"If I say I'm healthy, the first thing they'll do is hurt me tonight," Duvall says, unclear about who "they" are.

Best known for her role opposite Jack Nicholson in 1980's The Shining, Duvall, 67, last appeared on the big screen in the 2002 film, Manna From Heaven. Since then, Duvall admits to Dr. Phil that she's been alone "too much."
Dressed in sweatpants and a T-shirt, the two-time Emmy-nominated actress appears almost unrecognizable from the slender starlet many fans remember her as. While Dr. Phil points to her deteriorating health as a possible cause, Duvall claims that someone has changed her appearance in the middle of the night.
"I was a pretty girl," Duvall says. "I was beautiful."
"Shelley, you're still beautiful," Dr. Phil assures her.

In a career that spanned over four decades, Duvall has worked with some of the best in the business, and she looked back fondly on one of her former co-stars in particular -- Robin Williams.
"I had a great time on Popeye," Duvall says of their 1980 film together. "I loved Robin. He was so much fun to work with. He came up with the best jokes out of nowhere."
When Dr. Phil offers his condolences on Williams' 2014 death, Duvall reveals that she believes the late comedian is still alive.
"I don't think he's dead," Duvall says, explaining that she thinks Williams is "shape shifting."

"He looks real good in some forms and other forms he doesn't," Duvall adds, insisting that she has seen him.
Following the interview, Dr. Phil is happy to report that Duvall is currently receiving treatment from "a group of local professionals who, due to her refusal to take medication, will use alternative methods to treat her."
