1980-1987

In 1980, Cher penned her last disco song for the film Foxes, called Bad Love. The song can be found on the international version of The Very Best of Cher. Later in the same year, Cher formed the rock band Black Rose with her then-partner, guitarist Les Dudek, and released the album Black Rose by year's end. The album failed to sell, despite an appearance on The Tonight Show Starring Johnny Carson, and the band broke up the following year.

In 1981, Cher released her first Top 5 hit in UK in ten years: Dead Ringer for Love, a duet with Meat Loaf for his album Dead Ringer. In 1982 , Cher released I Paralyze, promoting it on American Bandstand and The Tonight Show, but critics panned the album and sales were disappointing.

With album sales and hit singles again at a standstill, Cher decided to expand her career into serious film acting. Her earliest entertainment ambitions had always lain in film, as opposed to music. However, she soon found herself in an uphill battle trying to land credible roles for a woman now in her mid-30s with little acting experience. At the time, she was quoted as saying that she didn’t really care if she ever made another record.

In 1982, at 36, Cher landed her first major role in a Broadway production of Come Back to the Five and Dime, Jimmy Dean, Jimmy Dean. Her performance was critically praised, and she was later cast in the film version, which was directed by acclaimed Hollywood director Robert Altman. She was next cast alongside Meryl Streep and Kurt Russell in the critically hailed drama Silkwood (1983) in which her character was a lesbian. She received her first Academy Award nomination, as Best Supporting Actress. She later won the Golden Globe Award as Best Supporting Actress in a Motion Picture - Drama for her performance.

Cher's next film was a starring role in the acclaimed Mask (1985), directed by Peter Bogdanovich. The film also starred Eric Stoltz, Laura Dern, Estelle Getty and Sam Elliott, and it was considered her first critical and commercial success as a leading actress. For her role as a mother of a severely disfigured boy, Cher won the Best Actress prize at the Cannes Film Festival.

In 1985, Cher was honored with Harvard University's Hasty Pudding Woman of the Year Award.

In 1987, she starred in three films: the thriller Suspect with Dennis Quaid; the dark comedy/fantasy film The Witches of Eastwick with Jack Nicholson, Susan Sarandon and Michelle Pfeiffer; and the romantic comedy Moonstruck with Nicolas Cage and Olympia Dukakis. For Moonstruck, directed by Norman Jewison, she won the 1988 Academy Award for Best Actress, the Golden Globe Award for Best Actress in a Musical/Comedy, and the Favorite Film Actress award at the People’s Choice Awards. 1987 was also noteworthy for the resurgence in Cher's recording career. After signing with friend David Geffen's label (Geffen Records), Cher released a self-titled album late that year which spawned her first major hit since 1979's Take Me Home. I Found Someone returned her to the Top 10 of Billboard's Hot 100. The Cher album was the very first 'platinum' certification (though not the last) of Cher's entire career. The follow-up single We All Sleep Alone reached #14; however, four additional singles culled from the album (Perfection, Skin Deep, Main Man and a new version of Bang Bang) failed to chart significantly.

On May 22, 1986, Cher made her infamous first appearance on Late Night with David Letterman. In her pre-interview with the show's producers, Cher had referred to host David Letterman with a derogatory term when asked why she had previously declined to appear on his program. He later confronted her about this on air during their interview, asking why she had refused so many earlier invitations. As she thought of an appropriate answer, he pushed her further saying, Because you thought... to which she suddenly blurted You were an asshole! to a shocked Letterman. She received a mixture of boos and laughter from the audience for the remark; however, Letterman quickly played off the incident as just fun. They patched up their differences for a 1987 show that had Cher and Sonny Bono reuniting to sing I Got You, Babe for what would be the last time. She has since made multiple appearances on Letterman's CBS show.

This was not the only time a chat show clash like this occurred. In 2001, Cher was interviewed by British talk show host and television presenter Clive Anderson (most famous for having the Bee Gees get up and walk out on a live interview after Anderson insulted them while they were on his show). Anderson sparked fury almost right away by saying, Wow, Cher, you look like a million dollars... is that how much it cost?
