Barbara Harris (born July 25, 1935) is an American actress who was a Broadway stage star and later became a film actress. She appeared in such films as A Thousand Clowns, Plaza Suite, Nashville, Family Plot, Freaky Friday, Peggy Sue Got Married, and Grosse Pointe Blank. Harris has won a Tony Award and has been nominated for an Academy Award and received four Golden Globe Award nominations.
Harris was born in Evanston, Illinois, the daughter of Oscar Harris, an arborist who later became a businessman, and Natalie Densmoor, an accomplished pianist. She began her stage career as a teenager at the Playwrights Theatre in Chicago. Her fellow players included Edward Asner, Elaine May and Mike Nichols.
She was also a member of the Compass Players, the first ongoing improvisational theatre troupe in the United States, directed by Paul Sills, to whom she was married at this time. Though the Compass Players closed in disarray, a second theatre opened by Sills called The Second City opened in Chicago in 1959 and attracted national attention. Despite Sills and Harris having divorced by this time, Sills cast her in this company and brought her to New York to play in a Broadway edition at the Royale Theater, opening on September 26, 1961. For her performance in this, she received her first Tony Award nomination.
