Akron's Ray Wise, who played Leland Palmer, is among the "Peaks" alums appearing. The official word:
Fans will be treated to a “Twin Peaks”-inspired episode of PSYCH scheduled to premiere on Wednesday, December 1 at 10/9c. Entitled “Dual Spires,” the episode celebrates the 20th anniversary of the cult favorite with guest star casting that includes Sherilyn Fenn, Sheryl Lee, Dana Ashbrook, Ray Wise, Robyn Lively, Lenny Von Dohlen and Catherine Coulson. Series Star James Roday serves as co-writer along with Bill Callahan.
The episode kicks off with Shawn (Roday) and Gus (Dulé Hill) receiving a mysterious e-mail inviting them to the annual Cinnamon Festival in Dual Spires, a quirky Northern California town nearly invisible on the map. When they arrive the pair quickly find themselves embroiled in the mysterious death of local high school student Paula Merral. As Shawn and Gus unravel the many secrets of the town, they meet several local residents including town doctor/lawyer/veterinarian Donna Gooden (Sheryl Lee), Sheriff Andrew Jackson (Lenny Von Dohlen), proprietors of the local diner Robert and Michelle Barker (Dana Ashbrook and Robyn Lively), the mysterious Woman with Wood (Catherine Coulson) and enigmatic bookish beauty Maudette Hornsby (Sherilyn Fenn). The pool of suspects proves to be deeper than suspected as Shawn and Gus must work to figure out who killed Paula Merral. Ray Wise reprises his role from last season as Father Westley.
Additionally, songstress Julee Cruise, who performed music during the original run of “Twin Peaks,” has signed on to perform the PSYCH Theme Song for the episode. The landmark series, that fashioned a widespread cult following, is celebrating its 20th anniversary this year.
