Other mistake: The officers working at the Smith Grove Sanitarium have "police" on their uniform patches. When Michael Myers was boarding the bus to be transported to a different sanitarium the bus had a Corrections Department decal. Since corrections officers run prisons and jails along with sanitariums, the uniform patches should have said corrections, not police.
Audio problem: At the babysitter house, her boyfriend Dave goes out and finds a motorcycle in the garage to the side of the house. He goes in and starts it, revving up the engine loudly. Several shots while he's doing this show the babysitter and the boy sitting in the boy's room reading and they are unable to hear the motorcycle that's blasting its engines loudly. However, moments later when Michael stabs her in that room and she screams, he is able to hear her scream through the house, through the closed front doors, through the yard and into the garage where he was trying to pick the motor cycle back up. How was he able to hear her scream through all that but they couldn't hear the bike which was considerably louder?Quantom X

Trivia: This will be the first film in the franchise with direct involvement from series creator John Carpenter since 1982's "Halloween III: Season of the Witch." Carpenter will serve as an executive producer on the film, in addition to writing the film's musical score. Carpenter, dissatisfied with the prior sequels and the 2007 remake, sought out to return to the series and guide the direction this film went in.TedStixon
