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.

Continuity: When Jamie is at the old Myers place she hides in the coffin - she also noticed Rachel dead in a chair, but when Michael goes berserk and Jamie takes off, running past the chair that Rachel was in, her body is gone.

Continuity: When Jamie and the officer wait in the upstairs room of Michael's old house, when you look at the window it is dark outside but then when it shows the doctor downstairs talking to Michael the sunlight is shining into the house.

Factual error: When Jamie and the cop are in the room upstairs and Michael is breaking through the door, The cop shoots ten shots out of a revolver without reloading.

Continuity: In the scene were Tina asks Michael to stop the car at the store he starts driving faster going at least 30mph for 7 seconds. When he finally stops and backs up he drives about 5-10mph and ends up outside the store in 4 seconds.

Plot hole: In the beginning, Rachel and Loomis are referring to Rachel's mother as being Jamie's step mother and Rachel refers Jamie as being her step sister. Rachel's mother is Jamie's foster mother and Jamie is Rachel's foster sister as said in Halloween 4.

Continuity: When Michael rams the pitchfork through Spitz, it is at the lower end of his back, nearer to his waist even. A few seconds later when Spitz's girlfriend comes at Michael with the same pitchfork, some other shots of the now dead Spitz show the pitchfork holes up near his shoulder blades, probably 6-8 inches higher than where they should be.

Audio problem: Watch closely to the scene right after Tina is stabbed and Billy is trying to pull Jaime away from her. There is a part where in the dimly lit bushes where Jaime keeps yelling "Tina", but her lips aren't moving.

Audio problem: When Tina is in the car with who she thinks is her boyfriend but is really Michael Myers; watch her lips when she says the line "Nothing Mike, that's what I get, Nothing." It is obvious that this line was dubbed in over something else as her lips do not match that particular line.

Other: In addition to the brake lights, there are no lights at all on the back of the car when you see it driven from behind. However, you can see that the lights are on from the front of the car.

Visible crew/equipment: While Mikey is shinning his car (as well as the stage light already listed as a mistake), as he goes along the side panel, just before the side mirror goes out of shot you can see the camera go past and a guys head in the reflection of the mirror.
