Other: In the beginning of Halloween 2, the scene where Dr. Loomis shoots Michael Myers repeatedly until he falls off the balcony is reenacted to reflect the events of the original Halloween. If you look carefully, you can see that the stuntman portraying Michael is actually walking backwards on a table until he haplessly falls off the balcony.

Continuity: The police claim the Myers house is at "45 Lampkin Lane." The address on the front porch clearly displays the number 709.

Continuity: In the credits, Michael Myers is said to be 23. However, the fact that he is supposed to be 21 in both films (because #2 took place directly after the first) is stated in both movies.

Continuity: After the explosion and Michael is walking on fire, you'll notice he is right next to the burning stretcher. Then they cut to a scene of Laurie hiding behind a water fountain. In the next scene of Michael, he is now about 8 feet behind the stretcher walking towards her again.

Continuity: In the scene where Marion is calling for help on the police car's 2-way radio, she speaks, "Marion Chambers with Doctor Loomis at the clinic; He's here." Right after that, the policeman on the other end of the radio starts to talk. However, Marion never lets go of the "talk" button on the radio's microphone, until the middle of the policeman's response to her request. You can't listen and receive anything on the radio while the button on the mic is pressed.

Visible crew/equipment: On the Goodtimes DVD release of Halloween 2, just after Dr. Loomis blows up the hospital room the camera switches to the hallway where Laurie is running away. The explosion comes through the hallway and you can see the right side of the hallway shaking - this shows that the wall is a studio set wall. You can also see wires behind it and the wooden supports that are holding it up.

Continuity: Notice how Michael is taking/reacting to being hit by the bullets at the conclusion of the first Halloween - you see him writhe in pain, his hand shake and grab near his side, and his body contort and literally twist before falling off the balcony - a believable shooting death scene. When the scene was re-enacted at the beginning of part II, all Michael does is lazily walk backwards and fall off.

Continuity: The flashing lights on the front of Bud and Jimmy's ambulance change places as they pull into the hospital driveway. They go from either the side of the hood to the front of the bumper.

Continuity: Dr. Loomis shoots out the passenger window of the marshal's car, but it seems to be intact in later scenes, like when the woman is outside using the radio calling for help.

Continuity: After Jimmy slips in Ms. Alves' blood, his position changes between the side camera shot and the above camera shot.

Continuity: At the end of the first Halloween, Loomis fires audible six shots from his gun (whether or not they all hit Michael is irrelevant). However, at the beginning of Halloween II, Loomis' gun can be heard firing off SEVEN shots.

Continuity: At the very end of the first Halloween, Loomis' first shot hits Michael while he is struggling with Laurie. A few seconds later, he is staring down Loomis and breathing very heavily. At the beginning of Halloween II, the scene is reenacted to reflect the ending of the first movie, but here you cannot hear Michael breathing at all after being struck by Loomis' first shot.

Continuity: During the scene where Jimmy the paramedic finds Ms. Alves in the major surgery room on a stretcher with the blood completely drained from her body, while turning to walk out, he slips and falls back first in the pool of blood. Later, he finds his way to his car where Laurie had been hiding and attempts to get help. If you look closely, the back of his shirt is still the same, but has no blood on it.

Continuity: When Annie's body gets wheeled out of the house and her father closes her eyes, her lids blink even though she should be dead.

Continuity: When Michael steals Mrs. Elrod's knife from her kitchen, about 6-7 drops of blood go onto the cutting board, and none are on the lunch meat she is using. When she comes back and notices the blood, however, now there are just about maybe 2-3 little smears of blood and one drop on the lunch meat.

Continuity: Towards the end of the film, when Dr. Loomis finally finds out Michael is at the hospital and orders the trooper's car to turn around. As the car turns around, the lighting outside appears to be pre-dawn however they arrive at hospital and it is still pitch black.

Revealing: When Doctor Loomis touches the blood in the beginning, you can see a bit of material (it appears to be plastic) sticking to his fingers as he pulls them up from the grass. It appears as though it was somehow involved in the effect of him touching the blood. (Perhaps to keep it from soaking into the ground?).

Factual error: At the end of the film where the blinded Michael is swinging his scalpel aimlessly, it makes loud "swooshing" sounds. This is pure fantasy. I have personally mimicked what Michael did using similar small scalpels and even larger knives without almost no sound when swinging them.

Revealing: When Janet spins the dead Dr. Mixter's chair around, you can see his right hand flinch.

Continuity: Michael comes into Laurie's room and stabs at her bed, only to find pillows had been placed there. He then walks out and leaves the door open. When Jill returns from checking on a patient, the door is now closed and she opens it.
