When the show was broadcast in the UK, many viewers wrote in to chide Charles Shaughnessy over his "fake" English accent, and suggested he practice with co-star Daniel Davis on how to do a proper English accent. The cast found this quite amusing, as Shaughnessy is a native Englishman born in London, while Davis is an American born in Arkansas.
During the show's fifth season run, both Lauren Lane and Rachel Chagall became pregnant. But unlike other sitcoms that hid their pregnant actresses behind props or had them sitting all the time, producers of this show made no attempt to hide or explain the growing bellies, except for one episode where C.C. makes a reference to Elaine on Seinfeld (1989) being hidden by props when she became pregnant and she is jokingly hiding herself with props.
"The Nanny" was more of a family affair than most shows since Fran Drescher's company produced the show and hired many friends and relatives to be regulars, guest stars and production staff. The show was also on six years without a major change in casting which was due in part to the congenial working conditions on the set of the show.
It's mentioned throughout the series that Maxwell passed on the musical "Cats", which has been noted as his biggest career mistake. In several episodes it's also mentioned that he passed on "Hair" and "Tommy" as well.
After cancellation of her sitcom Princesses (1991), Fran Drescher flew to Europe to meet her former co-star Twiggy. On her flight to London, she coincidently sat next to CBS executive Jeff Sagansky and talked him into a development meeting upon her return to Los Angeles. Subsequently meeting Twiggy and her children in London, Drescher came up with the idea of The Nanny (1993) and pitched it later to Sagansky convincing him to produce it.
Yetta's background changes throughout the show more than anything else in the series. She had her sweet sixteen on Ellis Island, she came to America with an arranged marriage, she got married in the old country, she fled Poland for her first wedding anniversary, she got married because she got knocked up by the seltzer man, she was on the Titanic, she was at Pearl Harbor; her story constantly changes. However, the show made a running gag out of Yetta's senility, so there is an explanation for the many contradictory stories about her past.
Throughout the series, viewers see that Maxwell has a brother (Nigel) and a sister (Jocelyn) but they are never shown in the same episodes. Also, in episodes where Nigel makes an appearance Jocelyn is never mentioned, and when Jocelyn is in an episode Nigel is never mentioned.
The producers planned to make the main character of Fran an Italian-American, but Drescher wanted the character to remain Jewish. The character of Val Toriello, however, is Italian-American, although Rachel Chagall is actually Jewish.
When the show was still being developed, the Sheffield family only consisted of two children: Brighton and Grace. The networked wanted there to be an older daughter that Fran could become a mentor for, so the character of Maggie was created.
Renée Taylor, who plays Sylvia, was originally billed as a guest star so that the network wouldn't be involved with her casting. She remained a guest star for the entire series although appearing in almost 100 episodes, including the entire final season.
According to the bonus features on the series box set, Brighton and Grace were names that creators Fran Drescher and Peter Marc Jacobson had picked out for their potential children. They divorced in 1999 and had no children.
After the pilot aired, the network thought that the character of C.C. didn't need to be an 'every episode' character and debated if she should be reduced to a 13-episode guest star during the first season.

When the ratings originally began to decline, the networks heads gave Fran Drescher and Peter Marc Jacobson a choice to either end the series at season five or marry Fran and Maxwell in season five to ensure a season six.
