Debbie Reynolds, an actress who sang and danced her way into film history opposite Gene Kelly in the classic 1952 musical “Singin’ in the Rain,” a movie that helped turn her into a sweetheart of American film, has died. She was 84. Reynolds, who was a major collector of Hollywood memorabilia and toured in a one-woman revue into her 80s, died Wednesday in Los Angeles, her son told the Associated Press.
