Courteney Bass Cox (born June 15, 1964) is an American actress and producer. She rose to international prominence by playing Monica Geller in the NBC sitcom Friends (1994–2004) and Gale Weathers in the horror film franchise Scream (1996–present). Her accolades include a Screen Actors Guild Award, nominations for two Emmy Awards and a Golden Globe Award, and a star on the Hollywood Walk of Fame.

Cox had a recurring role in the NBC sitcom Family Ties (1987–1989), and starred in the FX drama series Dirt (2007–2008), the ABC/TBS sitcom Cougar Town (2009–2015), and the Starz horror comedy series Shining Vale (2022–2023).

Phoebe Buffay is one of the six main characters from the American television sitcom, Friends. She was created by David Crane and Marta Kauffman and portrayed by actress Lisa Kudrow.

In the series' universe, Phoebe is the daughter of Frank and Lily Buffay. Her biological mother's name was Phoebe Abbott, whom she was named after. Phoebe has a twin sister, Ursula, a waitress who is also portrayed by Kudrow. Phoebe can speak several languages, including French and Italian. She appeared in all of the show's 236 episodes during its decade-long run, from its premiere on September 22, 1994, to its finale on May 6, 2004. She is a masseuse, notable for her offbeat and often unusual behavior. She was Monica Geller's roommate before Rachel Green, which is how she was introduced to the group. Phoebe is best friends with Monica and Rachel, along with their neighbors, Chandler Bing and Joey Tribbiani, and also Monica's brother Ross Geller. She plays acoustic guitar and sings simple, awkward songs at Central Perk, occasionally busking also. During the show's ninth season, Phoebe is set up on a blind date with Mike Hannigan (played by actor Paul Rudd) and they marry in the final season.

Rachel Karen Green is a fictional character, one of the six main characters who appeared in the American sitcom Friends. Portrayed by Jennifer Aniston, the character was created by David Crane and Marta Kauffman, and appeared in all of the show's 236 episodes during its decade-long run, from its premiere on September 22, 1994, to its finale on May 6, 2004. Introduced in the show's pilot as a naïve runaway bride who reunites with her childhood best friend Monica Geller and relocates to New York City, Rachel gradually evolves from a spoiled, inexperienced "daddy's girl" into a successful businesswoman. During the show's second season, the character becomes romantically involved with Monica's brother, Ross, with whom she maintains a complicated on-off relationship throughout the series. Together, Ross and Rachel have a daughter, Emma.

The role of Rachel was originally offered to Téa Leoni, the producer's first choice, and Courteney Cox, both of whom declined, Leoni in favor of starring in the sitcom The Naked Truth, and Cox in favor of playing Rachel's best friend Monica in Friends. A virtually unknown actress at the time, who had previously starred in five short-lived sitcoms, Aniston auditioned for the role of Rachel after turning down an offer as a cast member on the sketch comedy show Saturday Night Live. After acquiring the role and before Friends aired, Aniston was temporarily at risk of being recast because she had also been involved with another sitcom, Muddling Through, at the time, which was ultimately cancelled and allowed Aniston to remain on Friends.

Chandler Muriel Bing is a fictional character from the NBC sitcom Friends, portrayed by the late Matthew Perry. Chandler was born to Nora Tyler Bing, an erotic romance novelist, and Charles Bing, a gay female impersonator and star of a Las Vegas drag show called "Viva Las Gay-gas" as Helena Handbasket. It is revealed in the first season that he went to an all-boys high school.

Chandler's best friends are his roommate Joey Tribbiani, and Ross Geller, his college roommate. He met Ross's sister, Monica Geller, and her friend Rachel Green while visiting Ross's parents' house. Chandler was the first person to know about Ross's love for Rachel. He moved to New York City and lives across the hall from Monica. He meets Phoebe Buffay through her. Chandler has a very good sense of humor and is notoriously sarcastic, which he credits as a defense mechanism developed during his parents' divorce when he was a child. He is the most financially secure member of the Friends. He suffers from commitment issues, but he later marries Monica at the end of the seventh season. In the tenth season, Chandler and Monica adopt twins, Jack and Erica.

Joseph Francis Tribbiani Jr. is a fictional character, serving as one of the primary characters of the NBC sitcom Friends and the protagonist of its spin-off Joey. He is portrayed by Matt LeBlanc in both series.

Joey is an Italian-American struggling actor who lives in New York City with his roommate and best friend, Chandler Bing (Matthew Perry), and hangs out in a tight-knit group of his best friends: Chandler, Ross Geller (David Schwimmer), Monica Geller (Courteney Cox), Rachel Green (Jennifer Aniston), and Phoebe Buffay (Lisa Kudrow). He lived with a few other roommates when Chandler moved out to move in with Monica.
