In the 1960s, when it became clear that Adventures of Superman would continue to enjoy great popularity in syndicated reruns, far beyond the end of its production in 1957, Coates—like many of the other supporting cast members such as Jack Larson ("Jimmy Olsen")—tried to distance herself from the Superman series, fearing it might limit her opportunities. By the mid-1960s, however, she had settled into a comfortable semi-retirement as a wife and homemaker after marrying Los Angeles family physician Howard Press in 1962. She resumed her career after their divorce in 1986, but in the period immediately before that divorce, her film and television appearances were infrequent. One notable role was that of the mother of the female lead in the 1970 film The Baby Maker, directed by James Bridges, the lover and production partner of Jack Larson, who had remained Coates' good friend since they worked together on Adventures of Superman.
