Visible crew/equipment: Michael J. Fox is dancing on top of a bus as the Teen Wolf. The camera swings just a little too far toward the back of the bus and a police car that is escorting the camera car and bus is seen in the rear with its red lights going.
Other mistake: When Scott is delivering the hardware store supplies for the play, the cans of paint he is carrying awkwardly flip about like empty ones, and when he drops it makes a hollow sound. I'm sure they are meant to be full.

Continuity mistake: At the very end, Pamela tells her boyfriend to drop dead and walks away, off to her right. But a second later, in the last shot where Scott is hugging his girlfriend and his dad, if you look just to the lower left of them, not only is Pamela still just standing there, but she's to the left of where she was standing before.
Continuity mistake: When Scott turns into the wolf for the first time in his bathroom, the position of his blue coat on the toilet seat keeps changing.

Visible crew/equipment: When the wolf is "surfing" on top of his van, he does a hand stand, and you can see the handles he's holding onto for balance. They aren't there when they are surfing standing up.
