On the heels of news that Sherilyn Fenn will reprise her role as Audrey Horne for Showtime's "Twin Peaks" revival comes word that Laura Dern has been cast as a character that may be familiar to fans of the cult series.

Although Showtime isn't talking, TVLine theorizes the "Enlightened" actress could be playing Diane, the never-seen assistant to whom Agent Cooper addresses all of his tapes. The role (whatever it might be) reunites Dern with her "Blue Velvet" co-star Kyle MacLachlan and with David Lynch, who also directed her in "Wild at Heart" and "Inland Empire."

Dern joins a confirmed cast that (so far) also includes "Twin Peaks" alum Sheryl Lee and newcomers Robert Knepper, Balthazar Getty and Amanda Seyfried.

Production is under way in Washington ahead of an announced 2017 premiere.
