Continuity: After Sara and Freddy walk down the stairs after Michael Myers is hung, the curtain on the door behind Sara changes between shots, even when they peek through it.

Visible crew/equipment: Just after the garage has burnt down the police arrive and if you look very closely on the windshield of the first you can faintly see a camera crane lowering down.

Audio problem: When Sara enters the large room with the meeting with Freddy, Jen comes up to her and says 'Sara,' but her mouth doesn't move.

Continuity: When Sara is riding up the school pathway on her moped,beside her you see a boy pulling his bike along approaching his friends and he is about half a meter away but in the next shot the boy with the bike is about two meters away from his friends.

Other: When Freddy enters the kitchen dressed up as Michael Myers, he has a knife in his hand. Moments later, you see him yell at the real Michael Myers. Freddy has no knife in his hands and you didn't hear or see him put it down.

Continuity: When there is a four-way split-screen while they enter the house, the top-left, the bottom-left, and the top-right don't match properly.

Continuity: At the start just after Willy sees his partner's head in the washing machine, he gets his throat cut and there is blood all over the knife. Later on when Michael is approaching Laurie's room, his knife just has blood on the tip, only halfway up the blade.

Continuity: When Sara gets locked in the closet after the mannequin falls on her, we see Rudy's fist bust through the closet door, as if there were no other way it. In the next shot, the closet doors are wide open.

Continuity: Halfway through the film, we see Michael Myers walk into a room immediately followed by another Myers. Both are dressed nearly identically in a blue jumpsuit. But as soon as the first one turns around and we learn it's actually Freddie, the shot changes to Michael and back to him and he's wearing his jean jacket, seen in the rest of the movie.

Plot hole: What exactly was Laurie Strode's plan in the teaser, when she strung Michael up over the edge of the roof. From the way she starts cutting the rope it looks like she plans to drop him, but she's seen him survive a 2-storey fall before, in the original Halloween, not to mention multiple stab wounds in H20. A fall off the roof into bushes would barely phase Michael.

Audio problem: At the very end of the film Sara wants the fireman to open the bodybag with Michael Myers in it. When he does Freddy says,'Uh oh.', and as he says this the words do not match up with his mouth movements.

Continuity: After Sara receives a message saying that Michael Myers is still alive on her palm pilot Michael Myers stabs Freddy in his left shoulder but when it cuts to the close ups of the blade in his shoulder it is in his right shoulder.

Continuity: When you see Deckard is in his room with his friend the second time Deckard is relaxed,leant back on his chair with his cheek resting on his fist but in the very next shot he is typing on his computer.

Continuity: When Bill talks to himself in the mirror Michael bursts through the wall and grabs him but after you see the quick scene with Freddy and Nora having their glasses of wine Michael is completely out of the wall when he stabs him.

Continuity: Within a few minutes after entering Michael Myers' house Sara and Rudy go into the kitchen. Sara opens the door and a baby-chair fold out quickly, afterwards when they all take a look at it, there are no hinges or screws, etc. to make it flip open.

Continuity: When Freddy rendezvous with the gang, Jen's hair when she is applauding at the back is tied in two scruffy bunches sticking out. A couple of seconds later, she has only one bunch tied. From then on, it is tied in two bunches.

Continuity: When Michael Myers is holding the tripod to impale the crewman, the length of the sharpened end changes in length and shape numerous times. First, it's wider and smaller. Then it's slightly longer and narrower. And when it's finally through the victim, it's long enough to go through the neck and into the adjacent wall.

Continuity: When Michael Myers has Sara cornered, he rotates the knife in his hand so the blade is pointed down. After being knocked backward by Freddie, Michael advances forward and once again rotates the knife to point the blade down, yet he never changed it back.

Continuity: When Michael is walking towards Laurie's room in the sanitarium, the window on the door is yellow as if a light is on in the room. Then in the next shot it is blue as if a light was not on.

Continuity: Near the end of the film, Deckard is communicating to Sara's handheld device where Michael Myers is in the house. When Deckard tells Sara to "GO NOW!", the text has changed from small digital text to large bold font and the screen has changed from green to white, similar to a large PC monitor.
