Corrected entry: At the beginning, when Michael is about to kill his sister, we see through his eyes. When his sister turns around to see him, she has to look way up, meaning that he would be very tall, when in fact, he is only 6 years old.
Corrected entry: The bush that Michael hides behind is neatly trimmed on Laurie's side but bushy with leaves sticking out on the other side.
Corrected entry: On their way to babysit, Annie and Laurie run into sheriff Brackett who's investigating a recent break-in at the local hardware store. He reveals to the girls that the only things taken were "a couple of knives, some rope, and a Halloween mask." First, how can it be a break in if it's the middle of the day and the sign on the door says "OPEN"? Second, if we're to assume that Michael was responsible for stealing such a fine selection of items, why wasn't the break-in reported in the morning when Michael was already shown wearing the mask?
Corrected entry: When Annie drops Laurie off at Tommy's house the front door of his house is glass, but later it is a plain door.
Corrected entry: In the scene where Michael is stabbing his sister, the point of view camera is on his sister. But because the audience can't see what he's doing, the camera pans to the right to show the knife. Someone actually stabbing a person would not look away from the victim to watch the stabbing motion of the knife.
Corrected entry: Why didn't Doctor Loomis notice Michael's car until it was almost too late? The car was parked right across the street.
Corrected entry: When Laurie stabs Michael in the head with her knitting needle, she stabs him in the upper left part of his head, but in the next shot the needle is now in the left part of his neck.
Corrected entry: When Michael gets shot by the doctor, he falls off the balcony. In the next shot, the doctor pulls the trigger again. What was he going to shoot at?
Corrected entry: When Michael is going through the dining room, you can see the clock says 10 o'clock. But when he is going up the stairs you can hear the bell chime 12 times signifying 12 o'clock.
Corrected entry: In the beginning after Michael goes upstairs to kill his sister, he picks up the clown mask. But right before he picks up the mask the camera runs out of film and they have to reload the camera and there is a half a seconds pause of a black screen.
Corrected entry: At the end of the film when they show the different scenes in stills, the knife is shown on the floor by the sofa. Laurie had dropped it earlier after stabbing Michael with the knitting needle. He then has it again upstairs when she's in the closet. He drops it after being stabbed with the hanger. She picked it up when she stepped over him getting out of the closet and dropped it by the bed. How did the knife get back downstairs on the floor for the final stills?
Corrected entry: When Laurie spots Michael standing behind the clothes line the shot goes from Michael, to Laurie, and back to the empty spot where Michael was standing. However, Laurie never actually looked away from the area, only the camera did, so why is she so frightened when he is gone. She throws the window shut and back away, surely she saw him walk away...
Corrected entry: In the opening scene, after young Michael comes out of the house with the bloody knife and his parents see him, they only utter the words "Michael?" and stand there, staring at him with their hands in their pockets. Don't you think they would be curious as to why the knife is bloody and go inside? They don't seem disturbed at all.
Corrected entry: When Loomis shoots Michael and he falls over the balcony, you can see that he hopped over it and did not just fall.
Corrected entry: In the part where Michael Myers is driving down the street, watching Laurie and her friends walk home from school, the camera is supposed to be filming from Michael's point of view. However, they shoot it from the backseat, looking out the window. (You can see the metal grill seperating the front and back.) If Michael is driving the car how can he be sitting in the backseat?
Corrected entry: When Annie is taking her clothes off, her underwear is a solid colour, but in the laundry room it is polka-dotted.
Corrected entry: Michael Myers escapes from prison when he is 21. He is able to drive a car even though he has been incarcerated since childhood. Where did he learn to flawlessly drive a car during those years?
Corrected entry: When Annie goes to her car to pick up her boyfriend Paul the car is locked. she gets her keys and she then opens the car door without unlocking it.
