Not only is James in it, but the cast also includes Tom Cavanagh (from Ed), Sharon Lawrence (NYPD Blue), and Currie Graham (Men in Trees), along with two Supernatural alumni: Brendan Fletcher (Max in Nightmare) and Jessica Harmon (Lily in AHBL1).
They don't say who's playing Gary Ridgway, but there are two guys with no character name listed: James Russo and Jason Stewart. My money's on Russo...he ALWAYS plays the nutjob. On the other hand, this Stewart guy is pretty unknown. *shrugs* I'm only here for Spikey-poo anyhow.
I don't get this channel, otherwise I might find myself tuning in.
Oh yeah, there's also some dude named Steed in it. No shit...Steed Crandell. I can only hope that's a stage name.
