Anne Baxter 1970s in "Applause", the musical version of "All About Eve", but this time as Margo Channing (succeeding Lauren Bacall). In the 1970s, Baxter was a frequent guest and guest host on "The Mike Douglas Show". She portrayed a murderous film star on an episode of "Columbo", called "Requiem for a Falling Star". In this episode, she portrayed a fading movie star called Nora Chandler, perhaps in homage to the fading star Margo Channing of "All About Eve". In 1971, she had a role in "Fools' Parade" as an aging prostitute who helps characters played by Jimmy Stewart, Strother Martin, and
All About Eve for the aging diva role, before giving it to Bette Davis. Davis, who had recently ended an 18-year association with Warner Bros. after several poorly received films, immediately accepted the role after realizing it was one of the best she had ever read. Channing had originally been conceived as genteel and knowingly humorous, but with the casting of Davis, Mankiewicz revised the character to be more abrasive. Mankiewicz praised Davis both for her professionalism and for the caliber of her performance. Anne Baxter had spent a decade in supporting roles and had won the 1946 Academy Award for Best Supporting
