Jennifer Jason Leigh has become the latest big name to join David Lynch’s upcoming new installment of his groundbreaking 1990 mystery series Twin Peaks, I have learned. The Showtime project has been shrouded in secrecy, so nobody is commenting, but Leigh’s casting was unofficially confirmed when paparazzi photos from a night shoot in the Mojave desert earlier this week included a grainy shot of what looked like Leigh filming a scene with star Kyle MacLachlan. Original co-star Sheryl Lee, who plays Laura Palmer, also was snapped.

Leigh is joining a number of new Twin Peaks additions, with the list reportedly including Prison Break‘s Robert Knepper, Brothers & Sisters’ Balthazar Getty, and Big Love‘s Amanda Seyfried. I hear Lynch has been trying to get other well-known actors too, including movie star Naomi Watts who got her break in Lynch’s Mulholland Drive.

Lynch is directing the new Twin Peaks installment from a script he co-wrote with fellow Twin Peaks co-creator Mark Frost.
