Corrected entry: In the trailer to Halloween II, the man coming out of his house asking Loomis what was going on (right after Michael had been shot) and stating that "He had been trick or treated to death tonight" was a British man probably in his 60's. In the actual movie, however, that man was now a completely different guy who was probably in his 30's or 40's, with an American accent.
Corrected entry: Right as Laurie is being wheeled in an emergency room and the nurses and staff are preparing her, one of the nurses asks where Dr. Mixter is, and another one replies that he "is" ("is as in at the present) at the same party her folks were at, and that he was real drunk. However, a few seconds later, Dr. Mixter walks in and asks someone to get him some coffee.
Corrected entry: After Dr. Loomis, Marion, and the police officer enter the hospital, Laurie screams for help and climbs to her feet. She turns, and sees Michael Myers standing a few hundred feet away, next to a red light. Why is he so far away from her outside? He could've just gone out the doors that Laurie went through, which would've been much easier and logical.
Corrected entry: In the elementary school, Dr. Loomis spots Nurse Chambers and exclaims, "Oh, I hardly recognized you!" Although Nurse Chambers is wearing more make-up and is not dressed in a nurse's uniform, certainly Loomis would easily "recognize" a person with whom he shared an intimate, life-imperiling experience the night before, when Michael Myers stole their station wagon and fled the sanitarium. "Hardly recognizing" Nurse Chambers would have been a more appropriate response if the actual three year span between Halloween and Halloween II had occurred rather than the one night that was supposed to have elapsed between sequels.StraightOuttaCompton
Corrected entry: In the climactic scene in the operating room, Laurie says "Michael, stop!" before shooting him, but her mouth doesn't seem to move.
Corrected entry: During the scene where Jimmy finds Mrs. Alves dead on the stretcher in the MAJOR SURGERY room, there is a large light on in the room. A few minutes before Michael dies at the end of the film, camera shots are seen panning throughout the hospital and hallways, one of which is the MAJOR SURGERY room. This time, the light is off. We do know Jimmy made his way out to the parking lot to get help after he slipped on Mrs. Alves' blood in that room, but it's hard to imagine in his painful and disoriented state that he would stop and take time to turn off the lights in that room given the circumstances, especially since they weren't on a convenient wall switch anyhow.
Corrected entry: The security guard is sent to find the reason the phones do not work in the hospital. A couple of scenes later, you see a nurse chatting on a hospital phone.
Corrected entry: After Michael is shot, he gets up and goes into the people's house to get their knife. But if you notice the street before he goes in, it's completely quiet, but when he comes out it is crowded with people.
Corrected entry: Other than a patient that Jill responds to, no other patients or even visitors are ever seen or heard throughout the large hospital, despite the fact that the maternity ward has several newborn babies.
Corrected entry: In the original, after Dr. Loomis looks over the balcony to see Michael gone, he has a look on his face as if he knew something like this wasn't a big surprise (Michael surviving gunshots). But in the second film, not only is he in utter shock at Michael surviving, he repeats over and over in amazement during the film of how "he shot him six times without hurting him".
