Directed by: Christopher Landon
Starring: Vince Vaughn, Kathryn Newton, Celeste O'Connor, Misha Osherovich
Revealing mistake: Clearly not Vince Vaughn during the opening kills as the Butcher seems leaner than Vaughn.
Suggested correction: "Seems leaner" is just far too vague to be a mistake, and I didn't see anything that made me immediately think he was "clearly not Vince Vaughn."
Continuity mistake: During the final fight at the very end of the film, pay attention to Millie's bloody nose. At first, there's an equal amount on either side. But a few seconds later, the suddenly less blood on the left side of her face and more blood on the right side.
Millie (Blissfield Butcher): I want my body back.
Blissfield Butcher (Millie): Come and get it.
Trivia: Clearly a loving nod to Friday the 13th and Halloween movies here as the Butcher wears a mask similar to Jason's hockey mask in the opening scene, seems indestructible like both Jason and Michael, uses almost anything as a weapon and appears out of nowhere when his victims think they're safe.
