Shelley Duvall, the intrepid, Texas-born movie star whose wide-eyed, winsome presence was a mainstay in the films of Robert Altman and who co-starred with Jack Nicholson in Stanley Kubrick’s The Shining, has died. She was 75.

Duvall died Thursday in her sleep at her home in Blanco, Texas, her longtime partner, Dan Gilroy, announced. The cause was complications of diabetes, said her friend the publicist Gary Springer.

“My dear, sweet, wonderful life, partner and friend left us last night,” Gilroy said in a statement. “Too much suffering lately.  Now, she’s free. Fly away beautiful Shelley.”

Duvall was attending junior college in Texas when Altman’s staff, preparing to film Brewster McCloud, encountered her as at a party in Houston in 1970.

She would go on to become an Altman regular for the next decade, appearing in his Western opus McCabe & Mrs. Miller, the sprawling, critically acclaimed Nashville, the Paul Newman vehicle Buffalo Bill and the Indians, or Sitting Bull’s History Lesson and the motion picture version of Popeye alongside Robin Williams.

Emmy-nominated children’s shows

Duvall also appeared in a small role in Woody Allen’s Oscar-winning Annie Hall, as well as in Time Bandits and the Steve Martin comedy Roxanne.

In the 1980s, she helped create and star in the children’s television series Faerie Tale Theatre as well as its folklore followup, Shelley Duvall’s Tall Tales and Legends. The latter show as well as the 1992 animated short Shelley Duvall’s Bedtime Stories earned Emmy nominations.

In later years, Duvall encountered physical and mental health challenges, appearing on a controversial 2016 episode of Dr. Phil. Some television viewers and critics took aim at the show’s host for what they said was an exploitative segment.
