The show stars Matthew Perry, who also developed and executive produced the series, as the slovenly Oscar Madison and Thomas Lennon as the obsessively-tidy Felix Unger.

Felix and Oscar attempt to date Casey and Emily, two sisters who are roommates in the same building, and who both have recently exited their own unhealthy relationships.

Matthew Perry was a fan of The Odd Couple, particularly the 1968 film version, which served as the main source of inspiration for the revived series.

Perry and Danny Jacobson began developing the updated take on Neil Simon's classic as a multi-camera comedy at the network.

However shortly after announcing on August 30, 2014, that she was leaving Community due to a family emergency,[30] she was upgraded to a series regular role on October 6, 2014.

[37] In the episode, Felix (Thomas Lennon) asks Emily (Lindsay Sloane) on a date by saying, "Let's go visit that new Serbian restaurant, The Taste of Srebrenica."

The line seemed to reference the 1995 Srebrenica massacre, in which 8,000 young Bosniak men and boys were systematically rounded up and killed by the Bosnian Serb Army.

[40][non-primary source needed] On May 10, 2016, the show's executive producer, Bob Daily, apologized for the line, saying, "We were unaware of any connection to the terrible tragedy in Srebrenica.
