Hollywood is in mourning this week after the death of beloved actress Barbara Harris, who passed away on Tuesday after a battle with lung cancer. She was 83 years-old.

Harris’s death was confirmed by her close friend Charna Halpern, who said that the actress died in hospice care in Scottsdale, Arizona.

Harris was arguably best known for her role as Jodie Foster’s mother in the 1976 film “Freaky Friday.” In the movie, Harris and Foster’s characters switch bodies, and hilarity ensues. She was also known for her unforgettable performance in Robert Altman’s 1975 “Nashville,” in which she sang “It Don’t Worry Me” in front of a shell-shocked crowd after the violent climax of the movie.

Harris made her screen debut in 1965 with “A Thousand Clowns” and received two Tony nominations in the next two years for the hit Broadway musicals, “On a Clear Day You Can See Forever” and “The Apple Tree.” In 1971, she was nominated for an Oscar for best supporting actress for her performance as a struggling actress in “Who Is Harry Kellerman and Why Is He Saying Those Terrible Things About Me?”

Despite her success onscreen, Harris said that she was far more interested in the lead-up to a performance rather than actually performing.

“I used to try to get through one film a year,” she said in 2002. “But I always chose movies that I thought would fail so that I wouldn’t have to deal with the fame thing. . . . I’m much more interested in what’s behind acting, which is the inquiry into the human condition. Everyone gets acting mixed up with the desire to be famous, but some of us really just stumbled into the fame part, while we were really just interested in the process of acting.”

“I think the only thing that drew me to acting in the first place was the group of people I was working with: Ed Asner, Paul Sills, Mike Nichols, Elaine May,” Harris added in another interview. “And all I really wanted to do back then was rehearsal. I was in it for the process, and I really resented having to go out and do a performance for an audience because the process stopped; it had to freeze and be the same every night. It wasn’t as interesting.”

Rest in peace, Barbara Harris!
