“Diane, it’s 6:05 in the evening and… there are indications you’re about to be unmasked.”

Sources confirm to TVLine exclusively that Twin Peaks co-creator David Lynch has tapped his longtime muse, Laura Dern, to join the forthcoming Showtime revival in a pivotal role.

Details about Dern’s character are being kept under the tightest of wraps, but one tantalizing theory has the Oscar-nominated actress playing Agent Cooper’s never-before-seen secretary Diane. If true, that means Dern and Kyle MacLachlan would once again be paired as investigators, a super-cool nod to their roles in Lynch’s 1986 mystery noir Blue Velvet,

A Showtime rep declined to comment for this story.

In addition to Blue Velvet, Lynch and Dern worked together on 1990’s Wild at Heart and 2006’s Inland Empire.

Dern, who recently signed on to co-star in HBO’s star-studded limited series Big Little Lies, joins a growing Twin Peaks ensemble that includes vets MacLachlan, Sheryl Lee and Sherilyn Fenn, as well as newbies Robert Knepper, Balthazar Getty and Amanda Seyfried. (To date, the only piece of casting Showtime has officially confirmed is MacLachlan).

Lynch and fellow co-creator Mark Frost have penned all episodes of the present-day revival — which is rumored to total more than a dozen episodes — with Lynch directing every installment. Filming is currently underway in Washington state ahead of a Summer 2017 debut.
