Laura Dern is joining the cast of Showtime’s Twin Peaks revival. As with most other details about the show Dern’s role is top secret. TVLine reported the news.

Whatever it is, her role would reunite Dern with Kyle MacLachlan, her Blue Velvet costar. Additional cast members previously reported by Deadline include former Twin Peaksers Sheryl Lee and Sherilyn Fenn, plus Jennifer Jason Leigh, Robert Knepper, Balthazar Getty, Amanda Seyfried, Miguel Ferrer and Bailey Chase.

Lynch previously worked with Dern on Wild At Heart and Inland Empire. Alas, one Twin Peaks cast member Catherine E. Coulson, who played the Log Lady, won’t be returning. She died last September.

Twin Peaks co-creators Lynch and Mark Frost reportedly have written all episodes — with Lynch directing every installment. Filming is currently underway in Washington state. Showtime parent CBS CEO Les Moonves previously said the show would debut in 2017.

The series revival hit a snag in April 2015 when Lynch said he was withdrawing from the project over budget issues. CBS said at the time that talks were continuing, and in May Lynch tweeted that the show would go forward after all.
