Trivia

During a 20th anniversary screening of this film, Doug Jones revealed the moths that come out of his mouth at the end are real, not CGI. In a 2018 interview with Bloody Disgusting, makeup and special-effects designer Tony Gardner said that the actor wore a "mouth rig" a latex pocket attached to dentures that blocked off Jones' throat to make the moths come out "There was a small hole in the very back of the pocket so that Doug could cough some air through it ... An animal wrangler would place several moths in the pocket with tweezers, Then the stitches would be glued shut, and we'd run out of frame so that they could get to the shot as fast as possible," Gardner said.

Sarah Jessica Parker has said that she found being in the flying broom harness so comfortable that, instead of being lowered back to the ground during the extended downtime between certain takes, she would stash a copy of The New York Times on her person to read while remaining suspended in the air.

Sarah Jessica Parker plays a witch who was executed during the Salem Witch Trials. While researching her family history for the show Who Do You Think You Are? (2004), Parker was shocked to discover that her 10th great-grandmother, Esther Elwell, was arrested in Salem, MA in the late 1600s for committing "sundry acts of witchcraft" and choking a neighbor to death. Esther's case never went to court, she escaped with her life and the accusation ended the Salem Witch Trials. Parker said, "It has changed everything about who I thought I was."

The Devil's dog was Kathy Najimy's.

The role of Max Dennison was originally offered to Leonardo DiCaprio. He turned it down to appear in What's Eating Gilbert Grape (1993).
