Jetsons: The Movie

In the late 21st century, Spacely Sprockets and Spindles has opened a new mining colony on an asteroid. The proposed project is meant to increase productivity at 1/10 the cost of making the items on Earth. However, the factory continues to be sabotaged by someone or something. As Cosmo Spacely (voiced by Mel Blanc and Jeff Bergman) checks up on the "Orbiting-Ore Asteroid" again, the latest head of the factory, Alexander Throttlebottom, has run off, making it four vice presidents of the new plant that Spacely has lost so far. Fearing for his company (and profits), Spacely names George Jetson (voiced by George O'Hanlon and Jeff Bergman) as Throttlebottom's successor and sends George and his family to the plant. While the family is thoroughly upset from having to have been thrown from their normal life style (and the plans that they had that day), they set up apartments on the adjoining apartment community to the Asteroid and its neighboring shopping complex. While it takes the family time to adjust, Elroy Jetson (voiced by Patric Zimmerman) meets a robot boy named Teddy-2 (voiced by Dana Hill), whom he first is at odds with, but eventually befriends.
Teddy-2's father, Rudy-2 (voiced by Ronnie Schell), is the plant engineer and shows George around. Meanwhile, Judy Jetson (voiced by Tiffany) is having a hard time adjusting, and accepting the fact that she lost her chance at a date with rock star Cosmic Cosmo (voiced by Steve McClintock) (which a friend of hers later takes), but soon feels better after meeting a teenage boy named Apollo Blue (voiced by Paul Kreppel). George soon figures that he's ready to set the plant running again, and Mr. Spacely is all set to see the plant working full-throttle, and soon to churn out the one millionth Spacely Sprocket. However, the opening day festivities give way to panic as the factory is sabotaged once again. Over the next several days, George and Rudy-2 try to fix things, but the problems persist, to the point that Mr. Spacely heads on up to check on things. Thinking he has to take charge, George stays overnight, only to fall asleep and be taken off by the mysterious saboteurs. Elroy, Teddy-2, and their neighbor Fergie Furbelow (voiced by Russi Taylor) sneak into the plant, and meet Squeep (voiced by Frank Welker), a member of an adorable-looking alien race known as Grungees.
Squeep tells them (with Teddy-2 translating) that the factory is actually drilling into his people's community, which is based inside the asteroid. Soon, Jane, Judy, Apollo, Rudy-2 and Astro show up, and realize what is happening as well. George is found hog-tied in the Grungees' colony, and although he soon realizes just what the factory is doing, Spacely doesn't. Seeing his factory at a stand-still, he starts it up (after disconnecting Rudy-2, who tries to stop him), nearly burying Elroy and Squeep alive under rubble, and prompting everyone in the asteroid to get top-side, where George manages to shut down the factory and show his boss exactly what he's doing. After some talk, when George finally stands up to his boss, telling him that all he cares about is money, they come to an agreement: the Grungees will run the plant, and create new Spacely Sprockets through recycling old ones (thus stopping the further destruction of the Grungees' homeworld).
Spacely Sprockets reaches the millionth sprocket, and when George asks about being vice president, Spacely retorts, stating that "he's lucky that he'll be getting his old job back". Only when pressured by everyone else does he reluctantly promote him to vice president (without a raise). However, George knows that with the Grungees now running the plant, he is no longer needed as head of the Asteroid and will have to return home. The Jetsons then bid their new friends a tearful goodbye, including Fergie, who attempted to stow away aboard the Jetsons' car. They then head back to their apartment on Earth. As the family passes over the factory, the Grungees arrange themselves to form the words: "THANKS GEORGE", as a final grateful goodbye to him for saving their home.
