Played "Fern Magnin" in "Beverly Winwood Presents the Actors Showcase", performance was conceived and directed by Anthony Sepulveda (Groundlings Theatre, Los Angeles, California, USA).
Mike White wrote the part of Tanya McQuoid in The White Lotus (2021) with her in mind. They had worked together on Gentlemen Broncos (2009), and later went on a trip together, after White's partner canceled. According to Coolidge, a lot of the "unfiltered side" she exhibited on the trip, served as inspiration for the series.
