Scooby-Doo and the Alien Invaders

While driving the Mystery Inc. gang through the desert amidst a sandstorm, Shaggy Rogers accidentally drives onto government property before a UFO sighting causes him to crash near a small town. Shaggy and his dog Scooby-Doo stay with the group's van, the Mystery Machine, while the others head towards town to find help. Not long after, the pair encounter aliens who chase them into town. After reuniting with their friends in a diner, a waitress named Dottie says the locals have never seen aliens, but have seen strange lights and hear strange sounds at night. Chef Sergio adds cattle have vanished overnight, causing people to leave town. When a patron claims to have pictures of aliens, the gang travel to his home, only to learn he made paintings. Nonetheless, he offers to let them stay the night.

While sleeping on the roof, Shaggy and Scooby are abducted by the aliens before they are awakened in the desert by photographer Crystal and her dog Amber, who give them a ride back to the diner. While spending time together, Crystal claims she is an undercover government agent sent to investigate alien activity. Shaggy takes her to the caves where he and Scooby first encountered the aliens. They find gold deposits, but are chased by aliens and military police. Meanwhile, the rest of Mystery Inc. ask a local mechanic named Buck to fix the Mystery Machine, during which they meet Max, a member of SALF (Search For Alien Lifeforms). When Max takes them to meet the rest of his team, Laura and Steve, Velma Dinkley grows suspicious after seeing dried mud on the SALF team's boots. Taking her friends to a nearby canyon to confirm her suspicions, they find a dry riverbed along with mining equipment and gold within several caves before running into Shaggy, Scooby, Crystal, and Amber. The aliens capture Velma, Fred Jones, and Daphne Blake while the MPs cause the others to fall off a ledge. After the MPs leave to pursue them, the aliens reveal themselves as the SALF team, who discovered the cave is part of a 19th century gold mine. Due to it being on government property, they kept it hidden, concocted their alien disguises to keep others away, and hired men to impersonate MPs to help them further.

Concurrently, the MPs corner Shaggy, Scooby, Crystal, and Amber, but the latter pair reveal themselves as aliens to rescue the former pair before rescuing the others and subduing the SALF team. Crystal and Amber reveal further that they were the ones who caused Shaggy to crash and used television signals from the 1960s to disguise themselves before sharing a heartfelt goodbye with Shaggy and Scooby and leaving Earth. Afterward, the SALF team and the MP impersonators are arrested and Buck repairs the Mystery Machine, allowing Mystery Inc. to resume their journey.

Scooby-Doo direct-to-video films began with Scooby-Doo on Zombie Island in 1998, followed by Witch's Ghost in 1999. The first films had done so well that the studio considered Scooby-Doo a tentpole property that would sell "no matter what". Witch's Ghost had a troubled production, with studio executives insisting the team following a script written by outside screenwriters that the crew considered unsatisfactory. Unlike its predecessor, Scooby-Doo and the Alien Invaders was a largely smooth-sailing production, with little executives oversight.^[2] The film was written by Davis Doi and Lance Falk, with Glenn Leopold contributing some small elements.^[3] The theme song featured actress Jennifer Love Hewitt performing.

The movie was released on VHS and DVD on October 3, 2000 for $19.96 and $24.98, respectively.^[4] Special features on the DVD include:

• The Behind the Scenes special
• The Making of a Scooby-Doo! Video Game
• Scooby's Steps to Solving a Mystery
• Cast Fun Facts
• Trailers

On Rotten Tomatoes the film holds an approval rating of 80% based on five reviews, with an average rating of 5.5/10.^[5] David Parkinson of Radio Times, gave the film a three out of five stars, saying, "This cartoon adventure is the best of a spate of feature-length spin-offs from the much-loved TV series."^[6] Carrie R. Wheadon of Common Sense Media gave the film a 3 out of 5 stars.^[7]
