Has appeared on Lost (2004), playing the mother of the character Ben Linus. Ben is played by Preston's real-life husband, Michael Emerson; the age difference is explicable because Ben's mother died shortly after giving birth to him.
Preston met her now-husband Michael Emerson during the mid-1990s when they both appeared in a production of "Hamlet" at the Alabama Shakespeare Festival. Preston played Ophelia and Emerson played Guildenstern in the production.
