It's Always Sunny in Philadelphia (TV Series 2005– ) Poster

Trivia

Jump to: Spoilers (8)
Charlie (Charlie Day) and the Waitress (Mary Elizabeth Ellis) are married in real life.
Was almost canceled after its first season, but renewed at the last minute when FX executives decided to give it room to grow. It has gone from the brink of cancellation to being one of the highest rated and most popular shows on FX, and with its fifteenth season has become the longest-running live-action sitcom in television history. However, The Adventures of Ozzie and Harriet, which ran for fourteen seasons (1952-1966), still holds the record for most episodes at 435. In order for Sunny to surpass the earlier show (and if only 10 are made a season as been the practice for the last several years) it would therefore have to run through to 2048 (season 42).
The character of Dee Reynolds was originally going to be the voice of reason, but quickly became an equal participant in the gangs illicit and morally questionable schemes.

In June 2011, it was reported that Rob McElhenney had gained fifty pounds in the previous six months. McElhenney has stated that he noticed characters from other sitcoms get better looking as the series progress (because the budgets get bigger, and that means more and better make-up people), but McElhenny wanted his character to do the opposite. Co-star Glenn Howerton started referring to the character Mac as "Fat Mac". When McElhenney asked if he could be called "Big Mac", Howerton said he would call him "Big, fat Mac".

The show was initially titled, "It's Always Sunny on TV". The original, unaired pilot only cost two hundred dollars to make, and was shot on a digital camera, with the actors taking turns holding the boom. It was then shopped around to different networks, and was picked up by FX. They then moved the setting of the show from Los Angeles to Philadelphia, and re-shot the pilot.

Season six included an episode titled "The Gang Gets Successful" that was never aired on FX. In season seven, some of that footage was used for episode ten, "How Mac Got Fat". In addition to showing Rob McElhenney before his fifty-pound weight gain, the story explained that the Gang had a Dee-conceived plan to hire individuals who looked like them as "avatars," so they could enjoy their newfound good fortune. The story would continue with Mac's efforts to emulate his bodybuilder avatar going disastrously awry (and everyone else forgetting the plan about ten minutes after it was proposed).

A little-known fact is that Morena Baccarin of Firefly and Homeland once shot a pilot for the US sitcom It's Always Sunny In Philadelphia playing a transgender woman. It's a role she still wishes she could have taken. "I know those guys really well because we went to college together, and they were shooting this themselves before it became a show or a pilot and we were all unemployed in Los Angeles". She said in an interview: "I thought it was hilarious. When am I ever going to get cast as a chick with a dick? That's never gonna happen. So I was 'Hell, yeah, I wanna play that.' We had a blast but, unfortunately, when the show got picked up I was shooting something else, so I couldn't do it."

According to a May 2022 New York Times article by Michael Levenson, in 2018 a woman named Laura Young bought a marble statue of a man's head in a Goodwill store in Austin, Texas, for $34.99. Young, who had worked as an antiques dealer, thought it looked like an ancient Roman bust--and it in fact did turn out to date from the late first century B.C. or early first century A.D. She discovered that it had been in the collection of a Bavarian king until World War II, when it was likely looted from Germany by an American soldier and brought to Texas. During the nearly four years it took for Ms. Young to determine how best to return it to Bavaria, she kept it in her living room and affectionately named it "Dennis Reynolds," after the character in It's Always Sunny in Philadelphia--because, she joked, he was "a very difficult, cold, aloof, emotionless man that caused some problems for me." Eventually she arrived at an agreement to return the bust to the Bavarian government.

Fans were shocked and saddened watching the season 12 finale because the character of Dennis seemed to exit the show. Glenn Howerton shortly confirmed afterwards that he wouldn't in fact be a series regular any more but that he would probably appear in some episodes moving forward. He ended up missing 4 out of 10 episodes in season 13 because he was leading A.P. Bio (2018), but returned full time in season 14. Rob McElhenney revealed in an interview that after doing season 13 with Howerton missing now and then, everyone realized that the show wasn't working as good as it used to, so season 14 was shot after season 2 of A.P. Bio to accommodate Howerton's schedule and have him available for every episode.

Dennis Reynolds occasionally declares that he doesn't have feelings. In addition, he frequently becomes aggressive and manipulates women and the gang to suit his own desires. All of this would make him a good candidate for Antisocial Personality Disorder (a sociopath), wherein he experiences an inability to socialize properly, and often resorts to substance abuse (further evidenced by his alcoholism and his addiction to crack).

Originally the creators had no intention on making Mac being out of the closet definitively because the comedic aspect of his hypocrisy worked really well for them creatively, but after seeing the fans reaction to season 11, in which Mac briefly comes out and then returns to the closet, they decided to have him be openly gay for season 12 because they realized the importance of representation with LGBTQI+ characters.
