Production has been under way for the past two months on Showtime’sTwin Peaksrevival series, but as of now, the only cast member the network has confirmed isKyle MacLachlanasSpecial Agent Dale Cooper. Over the past few months, numerous rumors and casting reports have surfaced revealing new and returning cast members coming aboard, but nothing official has surfaced from the network quite yet. Today, we have another casting report fromDeadline, revealing thatMiguel Ferrerhas signed on to reprise his role as FBI agent Albert Rosenfield in the revival series.

Miguel Ferrerappeared in eight episodes of the original series as the FBI forensics expert, who often clashed withTwin Peakssheriff Harry S. Truman (Michael Ontkean). Ironically, a report surfaced last month that revealed Michael Ontkean will not be returning, since he retired from acting several years ago. There has been speculation that the producers may try to re-cast the role. It has been rumored thatRobert Forsteris being courted to play Truman, but others contend that he may actually be playing a different lawman altogether.

The site also claims thatoriginal seriesstars David Patrick Kelly and Richard Beymer are coming back to reprise their roles as brothers Jerry Horne and Benjamin Horne. Other originalcast membersrumored to be returning are Mädchen Amick (Shelly Johnson),Sherilyn Fenn(Audrey Horne),Sheryl Lee(Laura Palmer) andDana Ashbrook(Bobby Brooks). It remains to be seen when and if these actors are confirmed by Showtime, but several of these actors have already been spotted in photos from the set.

New cast members includeAmanda Seyfried, Balthazar Getty,Robert Knepper,Peter SarsgaardandJennifer Jason Leigh, although nothing has been revealed about their characters yet. There have been rumors thatAmanda Seyfriedmay be playing the daughter of Dale Cooper andHeather Graham’s Annie Blackburn, but that has yet to be confirmed. It isn’t known how many more original cast members are slated to come back, and how many new characters have yet to be cast.
