This news is from June 21, 2021, but I did not see it until today.
Joanne Linville, who played the Romulan commander in a memorable 1968 Star Trek episode and had scores of other screen credits, died Sunday (6/20/2021). She was 93. CAA made the announcement but did not disclose a cause of death...
But despite her prolific active career from the mid-’50s to the late-’80s, and included a few latter-day roles, Linville is best remembered for her role in a 1968 episode of the original Star Trek. “The Enterprise Incident” is one of the few times Leonard Nimoy’s Spock character Spock romanced a woman. Linville played a powerful Romulan commander who is drawn to and ultimately seduced by the Vulcan’s charms. She discovers too late that Spock’s attentions are a ruse so that Captain Kirk can steal the fabled Romulan cloaking device, which renders ships invisible.
