Shelley Alexis Duvall (July 7, 1949 – July 11, 2024) was an American actress and producer. Known for her distinctive screen presence, portrayals of eccentric characters, and later productions in children's programming, her accolades include a Cannes Award and a Peabody Award, in addition to nominations for a British Academy Film Award and two Primetime Emmy Awards. Four of Duvall's films have been preserved in the National Film Registry by the Library of Congress as "culturally, historically, or aesthetically significant" as of 2025.
Duvall was born in Fort Worth, Texas, and raised in Houston, Texas, and was initially interested in science. In 1970, she was hosting a party for her boyfriend of the time at her house, where she was discovered by filmmaker Robert Altman. Impressed by her upbeat personality, Altman cast her in the black comedy film Brewster McCloud that same year. She rose to fame by collaborating with Altman throughout the 1970s, appearing in the Western film McCabe & Mrs. Miller (1971), the crime film Thieves Like Us (1974), and the musical Nashville (1975).
