Continuity mistake: When Willie dies, Howie says 'he's gone' but Willie's head position changes between shots. (00:24:55)
Deliberate mistake: The shot of Willy running away from the parked car is taken from the episode where Elias is killed. Two things give this away - 1) Willy is wearing a different coloured jacket and 2) he is supposed to be seriously injured yet he sprints along the street. (00:08:50)
Revealing mistake: When John is holding the two mice, if you watch his left arm closely you can see his arm jerk beneath the table where he replaces the real mouse with an edible one. (00:20:50)
Continuity mistake: When Charles reads the message about Nathan Bates coming out of the coma, there are two things to look for during the closeup of the note. The logo on the top is replaced by writing and he grips the note in a different position from before. The writing changes yet again when the note is seen from behind. (00:13:35)
Audio problem: When Ham grabs Howie's armband and says 'our man' it's painfully obvious that the words have been dubbed by Marc Singer instead of Michael Ironside. (00:19:00)
