The Life and Times of Grizzly Adams

The Life and Times of Grizzly Adams is a 1974 independent feature film created and produced by Charles E. Sellier Jr. The film's popularity led to an NBC television series of the same name. The title character, played by Dan Haggerty, was loosely based on California mountain man John "Grizzly" Adams (1812–1860).
NBC aired the series finale of the TV series on February 21, 1982 by way of a two-hour TV movie called "The Capture of Grizzly Adams" where a bounty hunter used Adams' daughter, who was not seen or mentioned since the 1974 film, in a kidnap-extortion ploy to lure the fugitive mountain man back to civilization. In the end Adams proves his innocence.
In the television series, Adams had two human friends, an old mountain man trader named "Mad Jack" played by Denver Pyle who was often featured with his mule ("Number Seven"), and a Native American by the name of "Nakoma" played by Don Shanks. Adams, Mad Jack, and Nakoma helped myriad mountain visitors while protecting wildlife at the same time.
Plot.
The film portrays the somewhat fictional Grizzly Adams as a frontier woodsman who fled into the mountains after he was accused of a murder he didn't commit. While struggling to survive, Adams saves an orphaned grizzly bear cub he adopts and names Ben. The bear, while growing to its huge adult size, becomes Adams' closest companion. Consistently kind and gentle, Adams discovers and demonstrates an uncanny ability to gain the trust of most of the indigenous wildlife of the region, and he helps, sometimes rescues, takes in and tames many species. Originally a hunter, with his learned affection for wildlife Adams resolves never to harm another animal whenever possible. 
Cast.
In addition to Ben, there were many other named animals in the TV series, the most prominent being "Number 7", Mad Jack's ornery mule. Bart the Bear, then a bear cub, made one of his first acting appearances in the series playing Ben as a cub.
Production.
"Grizzly Adams" was created and produced by Schick Sunn Classic Pictures, a company based in Park City, Utah and operated by its founding executives, Patrick Frawley, Charles E. Sellier Jr., and Rayland Jenson. Parts of the film were shot in the Uinta National Forest, Wasatch National Forest, and Park City. The low-budget independent studio successfully introduced innovative marketing and promotional methods. Its 1974 "Grizzly Adams" movie was a runaway success. Produced on a small $140,000 budget, the film grossed over $45 million at the domestic box office and $65 million worldwide. It was the 7th highest grossing film of 1974. The 43% market share captured by a 1976 airing of the film on NBC led to network executives green-lighting the television series. The series drew a 32% market share, a significant figure to this day. The series also aired at a time when the environmental movement flourished.
Bozo was purchased from a Kansas zoo, and trained by R.E. (Bob) Leonard.
The show's theme song, “Maybe,” was written and sung by Thom Pace. The song was released as a single in Europe, where it reached number one, and in 1980 won Germany's Goldene Europa award for best song. At the beginning of each episode, part of the theme song is sung, while at the end, the entire theme song is sung. "Mad Jack" also introduces the circumstances of Grizzly Adams, referring to him as a "greenhorn", his friendship with Ben and all of the animals. After selling many products bearing the Grizzly Adams brand name, the brand was eventually trademarked by its creator, film producer, Charles E. Sellier, Jr. Following Sellier's death in early 2011, the brand rights were transferred to Grizzly Adams LLC.
Production for the series also took place in Utah, with location work in Arizona and Ruidoso, New Mexico, depending on weather conditions, due to the similarities in terrain. As with the film, animals were provided and trained by the Olympic Game Farm, housed at a second game farm built at Woodland. A scaled-down version of Grizzly Adams' cabin, used to make Dan Haggerty appear taller, is currently located at the Olympic Game Farm in Sequim, Washington.
