RIP Liev and his Gossip Girl-friend, as the new killer goes around tricking people with an electric voice-cloner. Lance Henriksen and Roger Corman are working on their Stab trilogy, a cover version of “Red Right Hand” playing on set, when Detective McDreamy comes to investigate why cast members are being killed off IRL. The two casts mix as Parker Posey, playing Fake Gale Weathers, is dating Dewey and tailing the real Gale for character tips, and all the worst characters get slashed as our old team takes their place. They all end up on an old Hollywood mansion as the movie becomes increasingly nonsensical, the closest to Freddy dream-logic these things have been (complimentary), topped by a pre-taped appearance by the rules-explainer-guy who wants to explain how trilogies work in the event of his death in part two. Killer is film director Scott Foley, McDreamy’s Grey’s Anatomy coworker.
