Scooby-Doo e gli invasori alieni

This is Mary Kay Bergman's last movie as Daphne Blake. She died by suicide in 1999, and this 2000 film is dedicated in her memory. Her friend, Grey Griffin, would provide the voice of Daphne Blake in all future Scooby-Doo movies starting with Scooby-Doo e il viaggio nel tempo (2001), which was released the following year.

The first time Scooby crawls through the small space on the bottom of the fence while he and Shaggy were chasing the jackalope, he gets stuck since he's too big to fit through it. After running while stuck in the hole for a few seconds while Shaggy climbs over the fence, Scooby pops out of the other side of the hole. The second time he crawls through it to follow Amber, he doesn't, but on the third time, he crawls through it again, he gets stuck again. Scooby pulls himself hard for a few seconds and manages to pull himself through with a pop. Amber fits well through it, but not Scooby.

The opening credits are shown on various planets.
