• Jennifer Aniston (Rachel Green): Born February 11, 1969, in Sherman Oaks, California. Known for her iconic haircut, "The Rachel," and her later film career in romantic comedies. She was the last of the six to be cast.
• Courteney Cox (Monica Geller): Born June 15, 1964, in Birmingham, Alabama. Originally auditioned for the role of Rachel, but convinced the creators she was a better fit for the "mother hen" Monica. She is the only main cast member to not receive an Emmy nomination for her role on the show.
• Lisa Kudrow (Phoebe Buffay): Born July 30, 1963, in Encino, California. An accomplished actress with a background in comedy, she famously played Ursula Buffay, Phoebe’s twin sister, on Mad About You before Friends began, creating a crossover universe.
• Matt LeBlanc (Joey Tribbiani): Born July 25, 1967, in Newton, Massachusetts. Before Friends, LeBlanc was famously down to his last $11 before landing the role of the lovable, dim-witted actor. He later starred in the spin-off series, Joey.
• Matthew Perry (Chandler Bing): Born August 19, 1969, in Williamstown, Massachusetts (Died October 28, 2023). His comedic timing and sarcastic wit defined the character of Chandler. He helped writers craft his character's iconic lines.
• David Schwimmer (Ross Geller): Born November 2, 1966, in Queens, New York. He was the first actor cast for the show, with the writers having his voice in mind for Ross Geller from the start. He also directed 10 episodes of the series.

The Deepest Secrets From The Set & Scripts

Many of the show’s most beloved elements were either accidents or last-minute changes. These facts showcase the show's evolution:

1. Monica and Joey Were Originally Supposed to Be the Main Couple

In the early stages of development, the writers considered pairing Monica Geller and Joey Tribbiani as the primary romantic relationship, rather than Monica and Chandler Bing. However, the undeniable chemistry between Courteney Cox and Matthew Perry, which became apparent after their hookup in London at the end of Season 4, convinced the creators to change the entire direction of the series.

2. The Show Was Nearly Called "Insomnia Cafe"

The title went through several iterations before landing on the simple, iconic Friends. Early titles included Insomnia Cafe, Friends Like Us, and Six of One.

3. Lisa Kudrow Genuinely Hated Playing the Guitar

Phoebe Buffay’s signature quirky songs, including the classic "Smelly Cat," were a staple of her character. However, actress Lisa Kudrow revealed that she actually hated playing the guitar. She only learned a few chords for the role and even suggested at one point that Phoebe should play the bongos instead.

4. Jennifer Aniston's Trifle Scene Was Truly Ridiculous

In a recent interview, Jennifer Aniston recalled filming "The One With Ross's Sandwich," where Rachel attempts to make an English Trifle. She noted that the actual trifle concoction—which included layers of ladyfingers, jam, custard, and beef sautéed with peas and onions—was "ridiculous in the best way" to film.

5. The Cast Hated the Iconic Theme Song

While "I'll Be There For You" by The Rembrandts is inseparable from the show's identity, the cast members themselves were reportedly not fans of the theme song and the opening sequence. They felt it was unnecessary to be dancing in a fountain, especially since the opening credits were not actually filmed in New York, but on a Warner Bros. lot in Burbank, California.

6. The Apartment Numbers Magically Changed

In the first few seasons, Monica and Rachel's apartment was number 5, and Joey and Chandler's was number 4. The creators eventually realized that these numbers made no sense for apartments in a high-rise New York City building. They were subsequently changed to 20 (Monica/Rachel) and 19 (Joey/Chandler) to reflect a more realistic, higher floor.

Guest Stars, Set Trivia, and Lasting Legacy

The show's high profile attracted a galaxy of A-list guest stars, often leading to fascinating, little-known stories about their appearances.

7. Bruce Willis Appeared for Free After Losing a Bet

Action star Bruce Willis guest-starred as Paul Stevens, the father of Ross's much-younger girlfriend, Elizabeth, in a three-episode arc. His appearance was not for a paycheck, but because he lost a bet with Matthew Perry (Chandler Bing). The bet was over whether their co-starring movie, The Whole Nine Yards, would hit number one at the box office. Willis lost and donated his entire fee to charity.

8. Courteney Cox Was the Real-Life Monica

Courteney Cox is well-known in Hollywood for her neatness, a trait she shared with her on-screen counterpart, Monica Geller. In fact, her real-life obsession with cleanliness and organization was so pronounced that the cast and crew often referred to her as "Monica" even when the cameras stopped rolling.

9. The Orange Couch Was a Studio Find

The iconic, oversized orange velvet couch in Central Perk was not a custom-made prop. It was a piece of furniture found in the basement of the Warner Bros. Studios lot.

10. The Magna Doodle Was a Running Gag

The Magna Doodle on the back of Joey and Chandler's apartment door was not just a piece of set dressing. It was a running gag. The drawings and messages were often created by a member of the crew, Paul Swain, who worked as an electrician on the show.

11. The Writers Used a Pie Chart for Fairness

To ensure that the six main characters—Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry, and David Schwimmer—had relatively equal screen time and equal lines of dialogue, the writers and producers reportedly used a pie chart to track their appearances and jokes. This was a key part of maintaining the ensemble dynamic and justifying their eventual equal pay of $1 million per episode.

12. The Pilot Episode Was Filmed Twice

The very first episode, "The One Where Monica Gets a Roommate," was filmed twice. The first version featured a different actress in the role of Monica's original roommate, who was quickly replaced by Rachel Green in the second filming, cementing the six-person dynamic.

13. Courteney Cox’s Pregnancy Was Hidden

Lisa Kudrow’s real-life pregnancy was written into the show as Phoebe carrying her brother’s triplets (Frank Jr. Jr., Leslie, and Chandler). However, when Courteney Cox was pregnant during the final season, the writers had to hide her bump using baggy clothes and strategic camera angles, as Monica and Chandler were infertile.

The depth of Friends's production, from the last-minute script changes to the incredible cast camaraderie, is a testament to why it remains one of the most beloved sitcoms in television history. These secrets, often revealed years later in interviews and retrospectives, keep the spirit of the show alive for both original fans and new viewers discovering the magic for the first time.
