Continuity mistake: In one scene, Jamie Lee Curtis takes a bottle of something out of the fridge, removes the top of the bottle and takes a drink, then hands the bottle over to her new boyfriend, he also takes the top off the bottle, even though it was never replaced - Jamie Lee Curtis can be seen playing with the top in her hands.
Continuity mistake: At the start when Jimmy opens the fridge door there are quite a lot of items in there. If you look to the right of the beer bottles on the lower shelf there is nothing but a purple box. In the next shot when he starts to take the beer out of the fridge you see that on the lower shelf beside the beer bottles there is a red object. (00:04:00)
Continuity mistake: At the end, Jamie Lee Curtis has two kitchen knives and continually stabs Michael until he falls off the balcony and onto a table. You can obviously see that it's a dummy because the dummy falls on its side if you look closely the right side of the table collapses, but then they switch to another shot with a real person and it now shows the left side of the table has collapsed.
Continuity mistake: When Jamie Lee Curtis hits Michael Myers with the van and they go over the cliff, you can see that the back doors of the van swing open, but when they get a frontal of Jamie going down the cliff in the van, the doors are shut, this happens about 3 times before the van finally stops.
Continuity mistake: When Will and Laurie are in the hall, it is Michael who comes up the stairs, as you can see the mask and hair. It's not until they cut away to Will and Laurie, then back again, that "Michael" becomes LL, and gets shot.
Continuity mistake: Although I understand the fact that H20 didn't want to include the Halloween 4, 5 and 6 timeline, Michael was burnt to a crisp by Dr. Loomis in the epilogue of Halloween 2, so he should have a fully burnt body. Also Michael was shot twice by Laurie in Halloween 2... He would have at least had scars/damage to his face in H20.Sean Kadlec95
