Among the four main cast members, Sean Hayes received most award recognition for his work, with a total of forty-four nominations, Megan Mullaly achieved forty nominations, Debra Messing got thirty-six, and Eric McCormack received twenty-eight, during the original eight season run.
As revealed in an interview, when Megan Mullally learned she won the role, she was leaving NBC studios and made an illegal u-turn. She was pulled over, but said it didn't matter, because she's on a new show.
One of only three television series to win Emmys for all of their principal cast members. The others are All in the Family (1971) and The Golden Girls (1985), with all three shows featuring a regular cast of four.
In a surprise announcement from NBC, this show returned to television after an eleven-year hiatus. What makes it all amazing is the show returned with the original cast, original director, original producers, and airing on the original network as well. The original announcement indicated there would be ten episodes, but NBC soon announced there would more coming.
Jack's website www.justjack.com really does exist. It now redirects you to NBC's Will & Grace website, but at the time it was created, it was an actual website created by "Jack". It included pictures, and a letter Rosario wrote to the I.N.S.
Former Vice President Joe Biden honored the show to be a trailblazer for acceptance of the LGBT community, as well as paving way for endorsement of same-sex marriage. He said, "I think 'Will & Grace' probably did more to educate the American public than almost anything anybody has ever done so far. This is evolving."
Originally, Max Mutchnick and David Kohan pitched a straightforward couples comedy in which a gay man and his straight female roommate were supporting characters. NBC liked the supporting characters better.
When Cher and Madonna made their respective appearance on the show, filming of their entrances had to be taken several times, as uproarious applause from the live studio audience ruined the audio tracks.
Megan Mullally once developed a Broadway musical which revolved around her character on this show, titled "Karen: The Musical". The musical would be centered on Karen Walker's rivalry with Beverly Leslie, with Leslie Jordan set to appear as well. Mullally secured the rights to the character from NBC, had backing from Fox Theatricals, and had lined up a director, and a composer for the show, before certain stakeholders in the Karen Walker character withdrew the rights for its use in the production.
Due to Debra Messing's pregnancy during the sixth season, Grace did not appear in five episodes: episode six, "Heart Like a Wheelchair", episode twenty-one, "I Never Cheered for My Father", episode twenty-two, "Speechless", episode twenty-three, "I Do", and episode twenty-four, "Oh, No, You Di-in't".
The Smithsonian's National Museum of American History exhibits memorabilia from the show, as a part of documenting the history of LGBT Americans. Featured are original scripts, casting ideas, political memorabilia surrounding the show, and the season eight finale, plus network donated props, such as a sign from "Grace Adler Interior Design", Will Truman's framed college diploma, the portrait of a young man that hung in Will and Grace's New York City apartment, as well as Karen Walker's pill bottle and flask.
Because of the show's numerous pop culture references, many of the celebrity guests had already been mentioned on the show before their eventual guest appearances (for example, Alec Baldwin, Matt Damon, Madonna, Britney Spears, et cetera).
The renewal in 2017 was originally only a limited return, featuring ten new episodes. This was expanded to thirteen episodes, but the day after the first table read, NBC announced the season had been expanded to sixteen episodes, and an additional season had been ordered as well.
In the episode where Grace is going to meet an old high school crush, he says he's part of a group of artists showing their art at the Zelman Gallery. Debra Messing's (Grace's) real-life husband is Daniel Zelman.
Karen Walker's husband, Stan, is never entirely seen. However, in Will & Grace: New Will City (2000), viewers do get to see parts of Stan Walker. He reaches out and grabs Karen's breast while she is talking to Will and throughout the scene, viewers can see Stan's legs, though most of him is blocked by a plant.
The part of Beverly Leslie, that was ultimately played by Leslie Jordan, was originally to be played by Joan Collins. The first episode with the character called for a fight between Karen Walker and Beverly Leslie wherein each character pulls off each other's wigs. At the last minute, Joan Collins refused to have her wig pulled off and Leslie Jordan was cast.
All of the four principal cast won an Emmy in their respective categories over the course of the shows run, with Megan Mullally taking home two for her portrayal of Karen Walker. However, only two years saw all of the cast nominated at the same time, 2000 and 2001. The show managed at least one win in any category, with the exception of two years, The 51st Annual Primetime Emmy Awards (1999), of which it was only nominated in one category, the direction of the pilot, and The 56th Annual Primetime Emmy Awards (2004), in which it was conversely nominated for nine. In only one of it's six nominations did it ever take home the Emmy for Outstanding Comedy Series.
During the episode in which Will and Grace compete for the Tenants Association Presidency, one tenant complains that her missing umbrella closely resembles the one belonging to "Tim Kaiser in apartment 12-B". Tim Kaiser was a Producer of the episode.

The 2017 revival disregarded the events of the final episode of the eighth season, in which Will and Grace had a falling out and only reunited a few decades later when their children attend the same university. This also meant disregarding the cliffhanger of whether Grace married Leo and had his child, or raised one with Will.
