Factual error: In one scene, Winifred asks Gilbert who Trask is and Gilbert replies that Trask is the "mayor", to which Winifred just acknowledges. However, the office of mayor was not created in Massachusetts until 1823, which is 130 years after they were hanged, so given the witch's lack of knowledge of the modern day, she would have likely not known what Gilbert meant.

Directed by: Anne Fletcher
Starring: Sarah Jessica Parker, Bette Midler, Kathy Najimy
Visible crew/equipment: During the flashmob, there are people walking toward the camera while dancing on the street. The shadow of the steadycam filming the scene is left of screen.
Winifred Sanderson: Lock up your children! Yes, Salem, we're back.
Trivia: Originally, Adam Shankman was attached to direct, but ended up getting attached to another Disney sequel, "Disenchanted," so he gave up the director's chair. Anne Fletcher was then selected to replace him. Ironically, Fletcher had previously been attached to direct "Disenchanted" about ten years prior, but left after production stalled. Both movies are finally coming out in 2022 as Disney+ originals.
