Harry and the Hendersons is an American sitcom based on the film of the same name, produced by Amblin Television for Universal Television.^[1] It aired in syndication from January 13, 1991, to June 18, 1993, with 72 half-hour episodes produced. It is about a family who adopts a Bigfoot called Harry.^[2][3]

Bruce Davison and Molly Cheek played the parents George and Nancy (in the film, they were played by John Lithgow and Melinda Dillon respectively) with Carol-Ann Plante and Zachary Bostrom as the children Sarah and Ernie (in the film, they were played by Margaret Langrick and Joshua Rudoy respectively). Kevin Peter Hall played the role of Harry in both the film and TV series, until his death late in the production of the first season. He was replaced first by Dawan Scott and then by Brian Steele in the third season (Steele had filled in for Scott in the Harry costume for numerous scenes during season two, before taking over the role full-time). Harry's vocal effects were provided by Patrick Pinney, where the vocal effects were previously provided by Fred Newman in the film.

In the series, George and Nancy were an upwardly mobile two-career couple, with the former working for a sporting goods company. George eventually launched his own magazine, The Better Life, late in the second season. Initially helping the Hendersons with Harry's care, and Sasquatch research, was Walter Potter, a biologist working for the Department of Animal Control. Also seen early on were the Glicks, neighbors of the Hendersons; Samantha was a pretty, young single mother and reporter, and Tiffany was her precocious little girl, a classmate of Ernie's who had an obvious crush on him. Samantha, Tiffany, and Walter were all written out after the first season, but the aspect of having a girl next door who chased after Ernie was retained through a new character, Darcy Payne, for the 1991–92 season. Darcy was more annoying than her predecessor, and spent all her waking hours trying to make the Hendersons' young son hers. However, she did catch on to the fact that the family was hiding a bigfoot, and had several close encounters with Harry; fortunately, Darcy disappeared from the show before she could have exposed the secret about him. Nancy's younger brother Brett, a photographer, moved in with the Hendersons in the second season, and was also sworn to secrecy about Harry. When George began The Better Life in the spring of 1992, Brett was hired as the publication's chief photographer and a financial beneficiary.

The following year brought many changes, as in the season premiere Harry's existence was accidentally exposed. Just as the Hendersons feared he would be captured by the government and possibly killed, he was rather embraced by the public and received overnight regional fame. For a while, Harry had to adjust to a high-profile life full of exhibition and additional scientific studies, but at the same time the entire family got used to resting more comfortably now that they did not have to hide the big creature from view anymore. Hilton, a friend of Ernie's and the son of a local police chief, joined the cast in the third season.
