Elizabeth Montgomery vs Agnes Moorehead
Rivalry year: 1967
Who won: Neither
The spellbinding onscreen mother-daughter duo went head-to-head in the Best Actress in a Comedy Series category only once, in 1967 — both losing to The Lucy Show's Lucille Ball. The rivalry only happened once: Moorehead, who played matriarch Endora to Montgomery's Samantha, had previously been up for an Emmy appeared in the Supporting Actress category; she return as a nominee in that category the following year. While they were each nominated numerous times, neither woman ever won for her role on the show, which ran from 1964-1972.
