The newspaper clip shown during the opening credits, which states that Laurie Strode died in a car accident, says that she was a survivor of the "Halloween murders" of 1968. They took place in 1978.

In the classroom on the blackboard, the spelling of W.B. Yeats's name changes from the incorrect spelling of "Yates" to the correct "Yeats."

The look of the mask changes back and forth for the scene where Charlie gets killed upstairs (the original mask was deemed unsatisfactory after principal photography was complete and some, but not all, scenes involving the mask were re-shot).

When two of the characters are watching Scream 2 (1997) on TV, the movie skips about five to ten minutes in five seconds.

Laurie removes the top from a vodka bottle, guzzles, hands the bottle to Will who also takes the top off.

In Loomis's office, there is a high school senior picture of Laurie saying "Class of '78". Halloween (1978) takes place in October 1978 and Laurie is still in high school, so she would have been part of the "Class of '79".

The original movie has dialogue suggesting that it is Friday. In actuality, Halloween 1978 was a Tuesday. This movie also suggests that it takes place on a Friday, but Halloween of 1998 was actually on a Saturday.

In one of the newspaper clippings, Michael's last name is spelled "Meyers".

Sometimes, even in real life, newspapers can make spelling errors.

Laurie drops a knife after stabbing Michael, but a moment later a knife is still in his chest. This is because she had two knives.

While the porch light of Nurse Marion's home is broken, the electricity is not off when Jimmy goes in; Michael cuts the electricity after Jimmy leaves.

The police investigation at the start of the movie is never mentioned again. This is because it was in a different jurisdiction in Illinois, whereas the majority of the movie takes place in California.

It's never really explained how Michael located Marion after 20 years since the events of Halloween and Halloween II, nor does it explain how he didn't locate her sooner.

The movie doesn't have to explain this, common sense dictates that in twenty years he was smart enough to track down the woman who was taking care of the man who was his psychiatrist for fifteen years.

When Michael hangs from the pipe at the school, Laurie's wound is visible before he stabs her.

When Laurie is driving the van with Michael in it, notice in the long shots the road is solid pavement or concrete, a very "beaten path," however, inside the van if you look outside the back window you can see the road is in excellent condition and has the yellow stripe down the middle separating the lanes.

In the opening scene, a woman holds up a knife before she stabs it into a pumpkin. There's a sound effect of the knife coming out of its holder, however, the knife is in the air the whole time.

When Laurie, John and Molly are running away from Michael to the car, John is pushed into the back seat, when the door is closed, a very bright stage light is reflected into the window.
