Coming in the wake of movie-to-TV adaptations nobody wanted, needlessly twisty thrillers nobody understands and even a few time-period-boosted successes nobody's excited about, Crazy Ex-Girlfriend is something fresh, unfamiliar and original.
"Crazy Ex-Girlfriend" is an American musical comedy co-created by Rachel Bloom and Aline Brosh McKenna. It was originally pitched to the Showtime cable service but was ultimately picked up by The CW. The show was retooled for network broadcast and expanded from thirty minutes to an hour. It premiered on October 12, 2015 and was eventually renewed three times for a total of four seasons. The show garnered critical acclaim and earned several awards over that time. Its last official episode aired on April 5, 2019, followed by a live one hour concert featuring the cast.
Screenwriter Aline Brosh McKenna had a movie idea about a crazy ex-girlfriend she had been developing for awhile. While on researching on the Internet she came across several of Rachel Bloom's online YouTube videos which had a similar theme. McKenna brought Bloom's talents onboard to help turn her movie concept into a musical television show. They met in May 2013 and began a collaboration eventually pitching an idea for the project in September of that same year. It was green lighted by The Showtime Network and together McKenna and Bloom wrote a script for the pilot between December and March of the following year. Director Marc Webb, who had done the romantic comedy/drama "500 Days of Summer", was tapped to direct the pilot. When Showtime ultimately passed on the project McKenna and Bloom shopped it around to various networks until The CW picked up the show in May 2015. Originally conceived as a thirty minute sitcom, it was changed to a longer forty minute format and additionally a lot of the more racier aspects of the show had to be toned down. After a few cast changes/additions and reshooting several scenes in the pilot the show premiered on the CW network on October 12, 2015.
