Revealing mistakes: Towards the end of the movie, Newton walks through a long, saloon-like room while the camera pans back. A lamp at the upper right part of the screen moves, probably touched by the camera crew.
Crew or equipment visible: When Newton opens the cabinet mirror in the bathroom we can briefly see the reflection of a crew member.
Continuity: During the first sex scene between Nathan Bryce and his student, her bra keeps changing from partially off to on to completely off to on again.
Continuity: When Newton lifts up the cookies in the desperate moment before the transformation, there were only twelve cookies on the plate, then, when they were shuffling in the air, it's easily possible to count at least sixteen of it.
Continuity: Newton only touches the plate once and there's only one plate of cookies, but when they were in the air, we can see two completely different lifting moments.
