On the Twin Peaks tribute episode
Most importantly, James wants people to either watch or record the first airing of the episode on Wednesday, December 1 because it is supersized with eight extra minutes of footage that will not be included in subsequent airings.
The episode came about because Twin Peaks is James’ all-time favorite show and at the end of the first season, he went to Steve Franks and said he wanted to do a tribute episode. Steve immediately got on board, but it has taken four years for Psych to build up the momentum and be in a place where they could do it right. According to James, who called the episode “a fan boy’s dream,” it was worth the wait. “It came out way better than I think it would have if we had done it earlier.” Admitting his bias, since he did co-write the episode, James still gushed, “I’ve never been prouder of anything we’ve done on Psych.”
On who’s in and out of the Twin Peaks episode
James said they started with a wish list of seven Twin Peaks actors they wanted and only two of the list (Michael Ontkean and Madchen Amick) couldn’t appear, but they got two others to appear in their stead. Appearing will be: Sherilyn Fenn, Sheryl Lee, Dana Ashbrook, Ray Wise, Robyn Lively, Lenny Von Dohlen and Catherine Coulson
When asked why Kyle MacLachlan or Lara Flynn Boyle weren`t asked to appear in the episode, James said that they didn’t ask MacLachlan because Agent Cooper was too iconic a character and because, as we’ll see in the episode, “Shawn and Gus become Agent Cooper.” Boyle, who didn’t appear in the Twin Peaks movie, wasn’t asked because they wanted the episode to be a “big love fest” and only asked the people they thought seemed most connected to the show and would have the most fun.
