Michael's full name is Michael Audrey Myers, yet in the mental hospital when someone is typing his name on a form they write Myers, Michael M (possibly character error).

Deputy Logan gets in touch with the sheriff on the radio and states that he "Just heard about the station." This was after Michael threw Bucky into the power grid and put the whole town in the dark, so Logan couldn't have heard about what happened from inside the house as he had to run to the car to get to his radio.

When Dr. Loomis parks his car outside of the gas station, he stops past the last gas pump. The next shot shows his car much closer and he tries to fill it up.

The burn scars on Dr. Loomis' face change periodically throughout the movie. There is a dramatic change from when he is riding in the truck with the preacher on his way to Haddonfield compared to when he arrives and comes into the police station.

Rachel's purse disappears and reappears when she sees Michael and runs from him while she is looking for Jamie.

Michael hides in the back of Deputy Logan's patrol car when the deputy drives from the Carruthers house to the Meeker house, and slips out unbeknownst to anyone after the deputy arrives. In reality, back doors on patrol cars could not be opened from the inside because this would allow a prisoner to escape from custody.

The patrol cars and uniforms read "Haddonfield Police Department," and several characters refer to the "police station," yet Meeker is a sheriff, not a police chief, and all of his men are deputies, not officers.

When Sheriff Meeker confronts the kids dressed as Michael, he says, "If I catch you again, it's a weekend in jail," which indicates it is a Friday. Halloween fell on a Monday in 1988.

Rachel dumps coffee on Kelly's white t-shirt, but it doesn't stain or even get wet.

Rachel dumps the coffee on the lower part of Kelly's t-shirt, mostly out of view of the camera.

Michael got his overalls from a mechanic he killed by impaling the guy with a metal rod in the chest area. Yet there is no blood or holes on the coveralls.

It's not confirmed that Michael is wearing the same man's overalls, he could have stolen another set from the gas station after killing the mechanic.

There is no reason for Michael's head and face to still be bandaged after 10 years.

People who have been badly burned need to have skin graft operations for years after their original injuries.

Loomis sets of an alarm when he breaks into the school, but once they are inside, the alarm stops. It's running again when the rednecks arrive at the school.

The alarm doesn't stop, it's only audible from the outside of the school.

When the security guard explains to the hospital staff what happened in 1978, he references Dr. Loomis shooting Michael Myers 6 times, then setting him on fire - Clearly referencing events from both Halloween (1978) and Halloween II (1981). However, Dr. Loomis shot Myers a total of 11 times (6 in the Wallace house, and 5 in the Haddonfield Memorial Hospital Emergency Room entrance) and then set him ablaze by causing a gas explosion.

Obviously, the security guard was not present at these events, nor did he have copies of the first two movies on DVD in order to nitpick how many times Michael was shot over the course of two movies - he would have been referencing the six shots that others would have witnessed at the Wallace house, and the fact that Michael was in a fire because of the burn scars, without knowing the full details of how the fire was started.

When Rachel is on the roof of the house and fighting Michael, she slides down the roof and slams into the chimney. When she does, the "brick" chimney flexes as though it's made out of thin wood.

When Michael is in the ambulance car after he grabs the guy on the head, he sticks his thumb in his forehead and on the left you can see the end of the fake arm.

After the power goes out, Jamie is on the sidewalk and hears Rachel calling for her. In the background, you can see tulips getting ready to bloom. Filming was obviously done in the spring rather than the fall.

In every scene before Myers is shot at or struck, it is obvious that there is protective padding under his coveralls.

During Brady's death scene, Michael is supposed to be lifting him up by the head. When Brady spits blood before dying, he's able to move his head freely, which makes it obvious that he has a foothold off-screen.

The patches on the medical personnel transferring Michael Myers read Smith's Grove, but the ambulance is labeled as Smith Grove.

In the scene where Brady loads the shotgun as Michael ascends the stairs, when Brady looks up, the front door can be seen directly behind Michael. This shouldn't be possible as they are on the stairs in the middle of the house.

Right after Michael throws Bucky, the electrical engineer, Bucky's false moustache starts falling off as he hits the cables.

When Rachel throws the cup of coffee at Kelly, we hear Rachel say "Have some coffee!" but her mouth clearly says something different.

When Dr. Loomis and Dr. Hoffman are in the mental hospital, Dr. Hoffman answers the phone. He says "I see. I see, thank you," but his mouth movements don't match the words. We then hear him yell, "Loomis! Loomis!" but he is clearly not actually yelling.

When Jamie is trying to escape from Michael when he grabs her by the foot, she tries to escape by grabbing the carpet and there are a lot of claw marks on the carpet, but in the next shot, some of the visual claw marks disappear.

When Jamie and Rachel get into the cop car and Sheriff Meeker drives off, you see Michael Myers standing in the road. Right before the scene ends, crew making the smoke blow are visible on the far left of the screen.

The cameraman is reflected in the window when Dr. Loomis runs to the window to look for Michael.

(at around 33 mins) A camera is reflected in the window when Rachel is getting up to go get Jaime.

When Rachel is waiting for Jamie to go trick-or-treating, as she gets up from the couch, the camera is reflected in the window.

Camera crew is reflected on the side of Lindsay's car as Jamie is getting into it.

When Loomis enters the police department and asks to speak to Sheriff Brackett, the deputy tells him that Brackett retired and moved to St. Petersburg, Florida, and that Loomis will have to travel 3000 miles south to see him. Haddonfield is located in Illinois. No matter what part of the state it is in, it would not be anywhere near 3000 miles away from St. Petersburg.

The movie takes place in Illinois, but the telephone at the insane asylum has an area code of 317, which is neighboring Indiana. In mitigation, Michael was described as a federal prisoner and could possibly have been transported across state lines.

Mountains are visible in the background in Haddonfield, Illinois; there are no mountains in Illinois.

When Rachel is looking for Jamie and sees Michael Myers, Michael seems to be ahead of her. But when Rachel sees him, she seems to be running towards him and not in the opposite direction from Michael.

In the ambulance, once of the workers said that Michael is a state ward because Jamie is too young to be his ward. He meant Jamie is too young for Michael to be her ward.
