Goofs:When the doctor examine Ronnie's "corpse" in the morgue, he pulls out the stake. It is quite obvious that he's struggling with a wooden stake that is placed on the actor's side, not through his chest. Moreover, the camera pans up and you can briefly see Ronnie's unharmed chest.

  • During the autopsy of the first patient, when the camera shows a close-up on the patient's neck where the bite marks are, you can see the actor's pulse right above them.
  • When Mulder breaks the chair in the motel room during his version of the story a hand is seen placing a stake onto the remnants of the chair. This is possibly deliberate because it adds to the comedic value of the two-story theme for this particular episode, with Mulder and Scully arguing about minute details.
  • During the first autopsy that Scully performs, we see the victim's body with the chest already open. Scully later says that she'll "begin with the Y-incision", but this has clearly already been done.
  •  I don't know if this is visible in all formats, but on the newest UK release on DVD, watching in widescreen, it's amazingly obvious. When Mulder recovers from the vampire attack, he gets up from the floor and breaks up a chair to make a stake. There is a shot of his feet as he smashes the legs off and bends to pick up a piece. In the bottom left hand corner of the screen, you can see a crew member's hand carefully and quickly placing a piece of wood on top of the pile for Mulder to pick up.
