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.

Mistakes
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. See more...
Trivia
Jimmy didn't die even though it never shows him after he falls on the steering wheel in the car with Lori. He simply passed out. In the TV cut it shows him alive, but for some reason in the theatrical version, they left it out. See more...

Halloween II mistakes
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: 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.
