Aside from Kyle MacLachlan, Showtime has yet to announce which original cast members will return for the highly anticipated revival of "Twin Peaks." But we now know at least one who won't be back.

TVLine reports that Michael Ontkea has decided not to reprise his role as Sheriff Harry S. Truman in the upcoming miniseries. “Michael is fully retired from show business, and has been for many years," said an anonymous source close to the actor.

According to the website, veteran actor Robert Forster, who made such an impact in the penultimate episode of "Breaking Bad," is rumored to have stepped in to play Twin Peaks' lawman. It's unclear, however, whether he's playing Sheriff Truman or a new character.

Forster joins a string of new additions to "Twin Peaks" that includes Peter Sarsgaard, Robert Knepper, Balthazar Getty and Amanda Seyfried.

“Twin Peaks” co-creators David Lynch and Mark Frost co-wrote the revival, which Lynch will shoot as a movie, and then edit into individual episodes (nine were announced, but Showtime anticipates there will be more).

Production is under way in Washington. Showtime hopes the miniseries will be ready for a 2016 premiere, but 2017 seems more likely.
