Hanna-Barbera Productions, Inc. (simply known as Hanna-Barbera and also referred to as H-B Enterprises, H-B Production Company and Hanna-Barbera Cartoons) was an American animation studio that dominated American television animation for nearly four decades in the mid-to-late 20th century. It was formed in 1957 by former Metro-Goldwyn-Mayer animation directors William Hanna and Joseph Barbera (creators of Tom and Jerry) and live-action director George Sidney in partnership with Columbia Pictures' Screen Gems television division. The company was sold to Taft Broadcasting in late 1966, and spent the next two decades as a subsidiary of the parent and its successors. Hanna-Barbera was known not only for its vast variety of series and characters, but for building upon and popularizing the concepts and uses of limited animation.
For over thirty years, Hanna-Barbera produced many successful animated shows, including The Flintstones, Yogi Bear, The Jetsons, Scooby-Doo and The Smurfs. Also, the studio produced many television movies, specials, theatrical films and commercials. In addition to winning seven Oscars, Hanna and Barbera won eight Emmy Awards, a Golden Globe Award, and a star on the Hollywood Walk of Fame, among other merits. The company's fortunes declined in the mid-eighties after the profitability of Saturday morning cartoons was eclipsed by weekday afternoon syndication. Hanna-Barbera was purchased from Taft (by then named Great American Broadcasting) in late 1991 by Turner Broadcasting System, who used much of its back catalog to program its new channel, Cartoon Network.
After Turner purchased the company, both Hanna and Barbera continued to serve as mentors and creative consultants. In 1996, Turner merged with Time Warner, and Hanna-Barbera became a subsidiary of Warner Bros. Animation. With Hanna's death in 2001, it was absorbed into its parent, and Cartoon Network Studios continued the projects for the channel's output. Barbera continued to work for Warner Bros. Animation until his death in 2006. The studio now exists as an in-name-only company used to market properties and productions associated with the Hanna-Barbera library, specifically its "classic" works.
In 2005, the Academy of Television Arts & Sciences honored Hanna and Barbera with a bronze wall sculpture of them and the characters they created.
In the opening scene, secret agent Rock Slag, who is physically identical to Fred Flintstone, is being chased through Bedrock. His pursuers, Bobo and Ali, think that they have finally killed him when they push him off a building. Meanwhile, the Flintstones and Rubbles prepare for a camping vacation which includes trying to drop Dino and Hoppy off at the veterinarian. On the way back, Fred crashes Barney's car, and they make a stop at the hospital where Rock Slag is also recovering. After Bobo and Ali find Rock and put him out of commission, Chief Boulder of the Secret Service enlists Fred to take his place in Paris for a special meeting. His assignment is to meet Tanya, the Green Goose's #1 lieutenant, who has agreed to turn over the evil Green Goose in return for a chance to meet the irresistible Rock Slag.
Boo-Boo Bear wakes up from winter hibernation, excited about the new Spring. Then Yogi Bear wakes up, his only interest finding some food to eat. Cindy Bear unsuccessfully tries to woo Yogi. After Ranger Smith thwarts Yogi's latest attempts to grab some food, Yogi gets angry and convinces Ranger to transfer him out of Jellystone National Park. Smith prepares Yogi to be sent over to the San Diego Zoo along with an identification tag. Yogi first says goodbye to everything, but tricks another bear named Corn Pone into going to California instead of him and Boo-Boo and Cindy remain unaware of this, thinking Yogi departed for good.
A stunt pilot trio called the "Flying Angels" (Scott Masterson, Chuck Gavin, and Beth O'Brien), are caught in a bizarre flash of light and crash, only to emerge unharmed. They are later informed by an agent of an interstellar peace-keeping agency (whose secret identity is the groundskeeper at a Pebble Beach golf course) that they have become the host bodies of warriors from the planet Altara in M78 to capture escaped monsters from the planet Sorkin who have arrived on Earth. They become the Ultra Force, headquartered within Mount Rushmore, and are assisted by a trio of robots, (the pint-sized Andy, the strong Samson, and the twitchy Ulysses). Although equipped with futuristic fighter crafts, inevitably one or more of the team is required to transform into an Ultraman, a gigantic red and silver superhuman being, to battle the monsters. After destroying the most powerful Sorkin monster, the constantly growing King Maira, the Ultra Force remains together to combat further threats to planet Earth.
Yogi leads his friends on a tour of the "Spruce Goose", the world famous flying boat, built by billionaire Howard Hughes. While touring, they were accidentally locked inside the plane. To make matters more worse, the dome where the plane was located closed up for the night. As the gang tried to get out, Augie Doggie tripped over and opened a door. Now the gang walked down a corridor and soon they came to the cockpit. While looking for a button or switch to open a door, Yogi pushed a button which magically activated the plane. Soon the gang exited the dome in the plane. In an attempt to avoid a bridge, Yogi pulls back the wheel, causing the Spruce Goose to lift off. A segment then occurs where the Spruce Goose is in outer space, and the gang begins seeing images of each other drawn in the stars. Later we saw two aliens Merkin and Firkin trying to invade earth by posing as "Earth people", but they were scared away from California by the Spruce Goose.
