After a while you get used to certain things: one of them is Barbara Walters cajoling the nominees on an Oscar night pre-show. This year will be her last. She began interviewing the likes of Audrey Hepburn and Warren Beatty in 1981. Now 80, Walters told The New York Times, “I just feel, ‘Been there, done that.'" About that Beatty, he was no fun. "Warren Beatty was the worst," Walters said. She was most charmed by Lauren Bacall, George Clooney, and Anthony Hopkins. This year's guests include Sandra Bullock and Mo'Nique.
