Jane Curtin vs Susan Saint James
Show: Kate & Allie
Rivalry years: 1984-1985
Who won: Curtin, 2
Saturday Night Live alum Curtin bested Saint James both times they wound up in the same category for Best Actress in a Comedy Series during the show's six-season run, from 1984-1989. (Curtin's wins came in 1984 and 1985 for playing Allie.) And perhaps Saint James took it personally, as she all but retired from acting when the show ended, appearing only sporadically in a handful of one-off roles in the years since.
