The Danza: Sarah Jessica Parker as Sarah Sanderson.
Executive Meddling: Positive example. The film was intended to be a Disney Channel Original Movie, but when higher-ups saw the script they felt it was strong enough for a theatrical release with well-known actors.
James Horner was originally supposed to score the film but pulled out due to scheduling conflicts and recommended John Debney to score the film (after Rachel Portman turned it down). Horner still did a theme for the film and is credited.
At one time, the song by Roxette, "Almost Unreal", was going to be used for the film in the end credits. However, thanks to a bit of Executive Meddling, it didn't make the cut, and ended up on the soundtrack for the film adaptation of Super Mario Bros. instead.
