Visible crew/equipment: When the punk Mikey was waxing his car, you can see a stage light in the reflection of the car.

Revealing: In the beginning when Michael crawls out of the mine shaft that was just bombed he floats downstream. You see that he floats up to the old man's dock. If you look at him you can clearly see that he is wearing a black lifejacket. The filmmakers didn't even try to hide it under his suit, it is clearly visible on the outside of his jumpsuit.

Continuity: The Myers house was a small Victorian house in all the others, but in this one its a huge gothic mansion!

Continuity: When Michael Myers is chasing Billy at the farm in the car, his position changes as he is driving - he is on the passenger side several times then on the driver side.
