Scooby-Doo and the Alien Invaders is the third in the series of direct-to-video films based upon the Hanna-Barbera's Scooby-Doo Saturday morning cartoons. It was released on VHS and DVD on October 3, 2000.


Mystery Inc. are stuck in the wrong place at the right time to investigate the claims of alien abductions in Roswell, New Mexico, all the while Scooby and Shaggy find their loves.


At the SALF station, Max, Laura, and Steve suddenly get a loud reading that's off the charts. When it disappears, Steve gets something on the radar.

The Mystery Machine is driving through a desert. A sand storm kicks in and Shaggy makes an accidental turn into government property. The sight of a UFO causes Shaggy to lose control of the vehicle and crashes into a cactus. Mystery Inc find themselves on the outskirts of a small town. While Scooby-Doo and Shaggy stay with the van, the rest of Mystery Inc. walk into the direction of a town ahead; they make it to a local diner to ask for directions. While waiting, Shaggy and Scooby fight over a Scooby Snack they find. Shaggy and Scooby then encounter a fictional animal called a jackalope. When they chase it into the mouth of a cave; they see a glow in the distance. Two aliens then approach them from behind and chase them towards a diner.

Shaggy and Scooby run into the diner in panic, claiming to have seen aliens. The diner waitress, Dottie, says that they never see the aliens but see strange lights and hear strange sounds at night. The chef, Sergio (pronounced "Serge"), says that a month ago, local cattle vanished overnight without a trace and a lot of people moved away. A man named Lester claims to have been abducted once before, and believes them. He also says that he has pictures; the gang goes to his house to see them, but they turn out to be nothing more than paintings by Lester. Lester then offers to let the gang stay for the night. Daphne and Velma sleep in a bunk bed and Fred sleeps on Lester's couch.

Scooby and Shaggy sleep on the roof, and are abducted. Scooby is the first to see the same two aliens they ran from earlier and wakes Shaggy. The aliens then touch Scooby and Shaggy's forehead while the two of them panic. The Aliens buckle them to beds. The aliens then put wires on them which tickle, Shaggy in the neck and Scooby on the side. Scooby manages to break free from the buckles and runs with Shaggy's bed in while the aliens pursue. Eventually they are trapped and a third alien comes forward with some sort of alien taser, the two black out. The next day the two find themselves in the middle of nowhere. They are awakened by a hippie-chick photographer, Crystal, and her golden retriever, Amber. Scooby and Shaggy fall head over heels in love the moment they lay eyes on them. Crystal and Amber give them a ride back to the diner, Scooby is making more moves than Shaggy. They meet the rest of the gang there with Lester who catch on to them being in love. They were so smitten that for the first and only time the pair have no appetite. When Crystal and Amber leave, Shaggy and Scooby get all washed up for when they can see them again. They go to a mechanic and ask if he can fix their vehicle; he says he'll look over it. They then meet Max who works at the SALF station; they help him load up oil. Crystal and Amber drive Shaggy and Scooby off to go looking for the Jackalope. Shaggy tries to make the Jackalope seem bigger, with no avail. Scooby picks flowers for Amber who gives him a kiss, Scooby rejoices greatly. When Shaggy tries the same thing a spider get into his shirt and he freaks out, still impressing Crystal towards the end.

Velma, Fred, and Daphne meet the crew of SALF. Velma becomes suspicious when she sees dried mud on their boots, since they are in the desert. Later, she decides to take the gang to a canyon where she presumes a river might run. The canyon proves to be dry, but they find mining equipment, and in the caves, gold. Meanwhile, military police make Shaggy, Crystal, Scooby-Doo and Amber leave the area as it's government property. Crystal then tells Shaggy she is really a government agent and not a photographer. She wants them to go back in. Shaggy and Scooby aren't sure, but when they use their charm on them they agree; Amber licks Scooby's cheek and he just laughs. Shaggy leads them to the cave where he first saw the aliens and saw the jackalope disappear. They quickly hide inside when the MPs come back, but are able to trick them into leaving by pretending that Scooby's tail is a snake. A real snake then scares Shaggy and Scooby into going further into the cave with Crystal and Amber close behind. They also discover the gold, but are then found and chased by the aliens and the MPs, the gang too.

The gang gets trapped in a net while Scooby and the others fall off a ledge after being cornered by the MPs. After the aliens send the MP's after them it's revealed that the aliens are really the SALF crew. They hold them hostage as they explain that they stumbled upon this cave when searching for ground to place another SALF dish. Since it was on government land, they decided not to report it, and plan to keep it that way. They are also revealed to be the aliens who abducted Scooby and Shaggy; the UFO was nothing more than a dressed-up helicopter, and the UFO interior was a movie set. Meanwhile, the others wake up and find themselves deep in the cave still close to another ledge.

When the MPs show up Shaggy and Scooby try to protect them by doing kung fu moves, the MPs aren't afraid. Crystal and Amber then scare them off by revealing their alien selves, but give the boys the credit. The MPs come running to the crew, but when all they see is Scooby and the others they send them back. This time when Shaggy and Scooby do the kung fu moves the MPs grab them and threaten them. Crystal and Amber then reveal their alien selves to all of them and scare the MP's off. Shaggy and Scooby didn't see the change so when they turn around and see them; they run off. The SALF members then try to capture them and as danger draws near Shaggy and Scooby come to the rescue and defeat the bad guys.

Crystal and Amber explain that they're aliens from a planet twenty light-years away from Earth, and that they had dressed and acted the way they did because they had gotten their information on Earth from TV and radio programs form the 1960s, and assumed that the people of Earth still talked and dressed like that. Also, it turns out that the UFO that ran the gang off the road near the beginning of the movie was actually Crystal and Amber's ship, which SALF had tracked. Crystal and Amber have to go back to their home planet, but they share a heartfelt goodbye with Shaggy and Scooby.

The SALF-agents are arrested by the authorities, and Buck comes by with the Mystery Machine all fixed up—Buck explains that the radiator patch he put on will hold until they get to the city and charges them $30 for it. Fred and the gang are happy that the van is finally fixed, and as Fred gives Buck the money for the repairs, he questions the mechanic on why he was out in the desert one day—Buck, though obviously very reluctant, reveals to Fred and the girls that a hobby of his is collecting pressed flowers, which was why he was out in desert that day. Fred and the girls are surprised to learn this, but note that the flowers Buck collected as very beautiful—Buck explains that he prefers keeping this particular hobby of his a secret, and Fred and the girls agree not to tell anyone.

After Buck leaves, Daphne notices Shaggy and Scooby staring up at the sky, obviously still sad about Crystal and Amber leaving. Fred and the girls feel bad for Shaggy and Scooby, but they help the duo feel a little bit better by giving them some Scooby Snacks.  The gang than drives away just as the Jackalope watches them leave.  It then looks up to the sky and sees a shooting star pass by in the sky.

Full credits

The following credits are how they are displayed on-screen (or as close as possible).

Opening credits

Closing credits


  • When Shaggy and Crystal are far away talking outside of the restricted area, he can be heard telling her about his and Scooby's first encounter with the Witch's Ghost from the previous animated movie.


  • After Warner Bros. pushed their own writers on Scooby-Doo and the Witch's Ghost, the crew were allowed freedom on this one. Glenn Leopold was credited for "story by" to get the residuals he lost on the previous one; although he did suggest the American Southwest setting and the jackalope for this one.[1]
  • This was the first film to be released simultaneously on both VHS and DVD.
  • Hollywood actress Jennifer Love Hewitt performed the "Scooby-Doo, Where Are You?" theme song for the film. The track was played when Shaggy and Scooby were being chased by the fake aliens.
  • This is the first production to be produced in the 21st century.
  • This film brings back the "crooks wearing masks" gag as the main element, where as it had been done as a minor plot for more focus on real monsters in the previous two films. The supporting characters, instead, turn out to be good, real inhuman characters (or essentially good monsters).
  • Although there have been a couple of other instances of Shaggy going on a date with a girl, and having a girlfriend, this movie marks the first real time Shaggy actually falls in love and debates the possibilities of a serious romantic relationship (with Crystal), leading to the daydream sequence of "How Groovy", another main movie track, performed by Scott Innes as Shaggy (and in part, Scooby-Doo) where he kisses Crystal on the lips. He does, however, get a real one near the end of film, making him the first main (human) character to get kissed—and on the lips, too. Scooby also gets kissed on the mouth by Amber.
  • Alien Invaders is notable for Mary Kay Bergman's final performance as Daphne as this film is dedicated to her. Grey DeLisle would take over after Bergman's passing.
  • Scooby-Doo is proven ticklish when one of the aliens tickles him with the wire attaches to Scooby's side.
  • Steve almost says the famous "And I would have gotten away with it, if it weren't for you meddling kids!" but as soon as he comes to "meddling kids", he is ordered to be quiet by a police officer.
  • This is the last Scooby-Doo animated production to be animated using hand-painted cels. All subsequent productions, beginning with Scooby-Doo and the Cyber Chase are colored digitally from here on.
  • While nowhere near as dark as the previous films, there are dark tones unique to this one, as Lester explains his abduction and subsequent experimentation (which isn't heard, but seen through Lester's movements, followed by the gang's horrified responses), and Scooby and Shaggy's own (implied) experimentations, showing SALF's highly immoral side.
  • After the end credits, Scooby scares the audience by wearing one of the alien costumes used by the SALF agents.
  • Burger King's Big Kids Meal line came with toys to coincide with the film, although none of them actually had anything to do with the film, instead it was based on the Scooby-Doo, Where Are You! The trailer also has the gang animated in their original clothes, instead of the updates.

Cultural references

  • There were three trailers released, with two of them parodying the theme song to the TV series The X-Files.
  • The opening of the film is similar to Star Trek: The Next Generation.
  • SALF (Search for Alien Life Forms) is a reference to SETI, which stands for Search For Extraterrestrial Intelligence. This is the collective name for a number of activities people undertake to search for intelligent extraterrestrial life. SETI projects use scientific methods in this search.
  • When Shaggy says, "Hey, come on guys, don't ya need to, phone home or something?", he references the movie, E.T. A similar reference occurs in the lyrics of the chase song, "The Aliens Are Here".

Animation mistakes and/or technical glitches

  • None known.

Inconsistencies/continuity errors and/or goofs/oddities

  • Velma is suddenly an expert on oil hydraulics when draws attention to the fact that the oil that they helped Max load into the SALF van is the wrong kind for hydraulics. How on earth did she figure that out? All that the viewers ever saw was gold-labeled cans with red flowers on them. The oil viscosity is never shown. Also, the dried mud that Velma saw on the SALF members' shoes is never seen either before or after Velma mentions it as a big clue that they're up to something!
  • Also, Velma's muddy shoe clue can be explained by the SALF crew venturing into town to buy supplies, for example. Just because they work in a clean facility does not mean that they are confined to it, after all they did encounter one of the crew members at the mechanic shop. This is not a real strong hint that the SALF crew is up to something suspicious.
  • 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.
