When the show first started George constantly referred to Tom as a honky. After a few seasons Sherman Hemsley asked the writers to stop having George call him that, as he felt that the characters were friends and that George would not use a racist term on a friend. When the writers refused to stop Hemsley simply mumbled the the word every time he said it, forcing re-shoots. Eventually the writers stopped using the word.
CBS never gave "The Jeffersons" a proper series finale. The cast, bitter that they never got a chance to say goodbye, reunited years later for a stage play based on the sitcom. Sherman Hemsley said he found out the show was canceled by reading it in the paper.
Like her character Helen, Actress Roxie Roker was married to a white husband (Sy Kravitz) in real life. During a casting interview, Roker was asked if she'd feel comfortable with her character having a white husband. She responded by showing the producers a photo of her husband.
Isabel Sanford did not want to do a spin-off. She told producers that she was happy with her recurring role on All in the Family (1971). When they told her that they were writing Louise Jefferson off of All in the Family, and moving the character to the Jeffersons with or without her, she decided to stay in the role.
In terms of number of seasons (11) and episodes (253), this is by far the longest airing All in the Family (1971) spin-off. In fact, The Jeffersons aired more seasons and episodes than All In The Family itself.
Marla Gibbs was given her own spin-off, Checking In (1981), where Florence went to work as an executive at a hotel. As a precaution in case the show failed, Gibbs would be allowed to return to "The Jeffersons". Roseanna Christiansen was hired as Florence's replacement, Carmen. When the spin-off was canceled after four episodes, Gibbs returned to the show. Roseanna went on to become the Ewing's servant on Dallas from 1982-1991.
Mike Evans left the show after the first season to work on Good Times, which he co-created. By the time his replacement Damon Evans quit the series, Good Times had been canceled, enabling Mike Evans to return to the role of Lionel for the duration of the series.
When The Jeffersons were first introduced on All In The Family, the family included George's brother Henry. Henry was never seen, and barely mentioned on The Jeffersons, as was the case on All In The Family after he was written off the series.
It was intended for Mike Evans to return full time for the series twelfth season under the premise of Lionel moving back to the apartment following his divorce from Jenny. This was an attempt to try to help revitalize the series, but the plans never came to fruition as a result of the show's unexpected cancellation following its eleventh season.
Both Paul Benedict (Bentley) and Irwin Keyes, who appeared in a recurring role as Hugo, suffered from acromegaly, a condition in which the anterior pituitary gland produces excess growth hormones, noticeably in the face.
While this show occasionally tackled controversial subjects like its parent show All in the Family, i.e. the Ku Klux Klan start having meetings in the building; or George getting stabbed by that female gang, most of the time the show featured light hearted fare, and was more of a black I Love Lucy or Honeymooners type show.
Mike Evans and Damon Evans alternated playing Lionel on The Jeffersons. Damon Evans came out of the closet after the series ended. He also said playing Lionel was a terrible experience and he wouldn't repeat it.
The Jeffersons is the longest running spinoff of All in the Family, outlasting even its parent show, which ran for 8 years and then spunoff into Archie Bunker's Place whereas The Jeffersons lasted for 10.
The last episode of The Fresh Prince Of Belair was a Jefferson's/Fresh Prince/Different Strokes crossover event, which had George Jefferson buying the Banks Mansion from Uncle Phil, after Arnold and Phillip Drummond are seen shopping for it.
From 1999 to 2002, reruns of the Jeffersons aired regularly on Nick At Nite. Ironically, Nick At Nite first officially debuted on July 1, 1985, one day before the final episode of the Jeffersons ("Red Robins") originally aired.
