In 1977, Exner published Judith Exner: My Story. Exner's memoir was adapted as a made-for-TV movie, Power and Beauty (2002), directed by Susan Seidelman, in which she was played by Natasha Henstridge. Material was added from accounts published after her 1977 memoir. Judy Campbell was portrayed in the 1998 HBO movie The Rat Pack by actress Michelle Grace.

In the episode In Camelot of the TV series The Sopranos, the character of Fran Felstein is based on Judith Exner.
