Shelley Duvall Reveals She's Battling Mental Illness On 'Dr. Phil'

Shelley Duvall, the beloved actress who's known for her roles in "The Shining" and "Popeye," has revealed she's suffering from mental illness.

In a sit-down interview with Dr. Phil McGraw, which will air on his show Friday Nov. 18, the 67-year-old discusses what her life has been like since she stepped away from acting after making her last film in 2002.

“I’m very sick, I need help,” she tells Dr. Phil during the interview.

Duvall became popular as an actress in the '70s and '80s after a small role in Woody Allen's seminal film, "Annie Hall." Afterwards, she was nominated for and won several awards for her work, including her role in "3 Women" and as a producer on "Faerie Tale Theatre." She was nominated for two Emmy Awards.

During the interview, Duvall claims that her late co-star, Robin Williams, has become a shape-shifter, that she's being threatened by the "Sheriff of Nottingham" and that she believes there's a "disc" inside her body.

Duvall is reportedly living in Blanco, Texas. She was married to artist Bernard Sampson from 1970 to 1974.
