Monica Geller

Monica E. Geller is a fictional character, one of the six main characters who appears on the American sitcom Friends (1994–2004). Created by David Crane and Marta Kauffman, and portrayed by actress Courteney Cox, Monica appears in all of the show's 236 episodes, from its premiere in 1994, to its finale in 2004. A chef known for her cleanliness, competitiveness and obsessive–compulsive nature, Monica is the younger sister of Ross Geller and best friend of Rachel Green, the latter of whom she invites to live with her after Rachel forsakes her own wedding. The two characters spend several years living together as roommates until Monica begins a romantic relationship with long-time neighbor and friend Chandler Bing, whom she marries. Unable to conceive children on their own, Chandler and Monica eventually adopt twins Erica and Jack and move out of their apartment into a larger house in the suburbs.

The creators' first choice for the role of Monica was comedienne Janeane Garofalo. Cox had been offered the role of Rachel but declined in favor of playing the character's best friend Monica because she was drawn to her strong personality. Meanwhile, the role of Rachel went to actress Jennifer Aniston. Before Friends aired, Monica's characterization was greatly debated among writers in regards to the character sleeping with someone on their first date during the pilot. Kauffman in particular greatly defended Monica, arguing with NBC executive Don Ohlmeyer over whether or not this would make the character too promiscuous. Ultimately, the episode aired unchanged after the studio surveyed the audience, the results of which returned in favor of Monica's existing storyline. The character's struggles with childhood obesity, challenges with romantic relationships and complicated relationship with her mother would eventually become popular staples of the show.
