History Trivia / ScoobyDooAndTheAlienInvaders

* InMemoriam: The credits feature a dedication to Creator/MaryKayBergman, where this was her final performance as Daphne. She passed away just weeks after recording, and the film was released posthumously.

* UnintentionalPeriodPiece: The fake [=MP=]s opened Crystal's camera intending to ruin the film, but instead find exotic (alien) circuitry inside. She explains it as being a digital camera. When ''Alien Invaders'' came out, film cameras were still commonplace while digital cameras were just starting to become mainstream, so the henchmen being unfamiliar with a digital camera, and even buying Crystal's explanation about the strange circuitry, was believable back then.
