Carrie Fisher made a wildly entertaining show about her story of growing up the child of Debbie Reynolds and Eddie Fisher: Wishful Drinking also became a popular HBO film. A casualty of her parents’ divorce with a sharply bracing sense of humor, Carrie Fisher now stars with her mother in a new documentary, aptly named Bright Lights. This week, the movie, to air on HBO, premiered at the New York Film Festival. Now 84 and living in Beverly Hills in a house next to Carrie’s, Debbie Reynolds missed this swell night. But she announced on the phone for the Alice Tully Hall audience: “I adore my children, and I’m not going to give up acting.” And then, because she loves to, she sang “I’ve Got You Under My Skin.”
