In 1970, she co-starred in Richard Altman’s comedy "Brewster McCloud." After starring in two more films, Duvall decided to make acting her career, she told the outlet.

"After ‘Thieves Like Us,’ Robert [Altman] looked at me and said, 'I knew you were good, but I didn't know you were great,'" Duvall said with tears in her eyes.

"It's the reason I stuck with it and became an actress."

Duvall first became known for her memorable portrayals of quirky characters, including Millie Lammoreaux in the 1977 drama "Three Women" and Olive Oyl in the 1980 live-action "Popeye" movie.

"All it took was to put on the costume, and I knew exactly how to play Olive," Duvall noted.

She shot to international fame when she starred as Wendy Torrance in "The Shining," Stanley Kubrick's iconic 1980 adaptation of Stephen King's horror novel.

Duvall admitted she has no problem watching herself on screen.

"On one channel there is ‘Popeye’ and another one ‘The Shining.’ Boy, those are two different films. … But in a way, it's like, 'Gosh, I was great.'"

"You didn't get paid much — just scale plus 10%. They thought women would just marry and the husband's going to support them. But that doesn't happen for everybody," she remarked.

Becoming Hollywood’s "unconventional It girl" at the time, she dated celebrities, including Paul Simon and Ringo Starr.

After announcing her retirement in 2002, Duvall moved back to her home state of Texas and stayed out of the public eye.

Once she discovered her brother was diagnosed with spinal cancer, she said it was "really important" for her to "get in touch with my family again."

Duvall’s new movie "The Forest Hills" is slated to premiere March 11 at a theater in New Jersey owned by Kevin Smith.
