Season Three is the further continuation of The CW musical comedy show "Crazy Ex-Girlfriend". Co-creators Aline Brosh McKenna and Rachel Bloom envisioned this as the third act of a four part story arc. Following the events in the Season Two finale, Rebecca Bunch was left at the altar by her fiancée Josh Chan and now plots her revenge on him. The Season Three renewal was officially announced on January 8, 2016.
- “It has nothing to do with numbers...‘Crazy Ex,’ ‘Jane,’ as franchises, have helped alter the perception of what the CW has become. When you have great critical work, critically acclaimed, award-nominated shows like ‘Crazy,’ it deserved to be picked up. Sometimes with critically acclaimed, great programming, you just [renew it] and hope that it finds an audience. In today’s fragmented world, [awards nominations] give you a calling card.”— Mark Pedowitz, The CW
On January 8, 2016 The CW officially announced at a Television Critics Association winter press tour that seven shows earned early renewals from the network. "Crazy Ex-Girlfriend" was one of them and was greenlit for a Season Three despite being the lowest rated show on the network. In an interview with Indiewire.com Co-creator Aline Brish McKenna hinted at more explorations of Rebecca's past:
- “The idea was, we’ve gotten to know her over 31 episodes, the audience has gotten to know her pretty well. But we don’t know anything about her past, really,” she said. “As Paula says, the best predictor of the future is the past. It stands to reason that somebody who engages in these obsessive-romantic behaviors has done so before.”— Aline Bosh McKenna
On May 18, 2017 an official press release by The CW announced that "Crazy Ex-Girlfriend" would return on Friday at its 8:00 PM timeslot. This time it will be paired again with the show "Jane The Virgin " which moves from its Monday former Monday night time slot to Friday and follows it at 9:00.
On April 5, 2017 some of the "Crazy Ex-Girlfriend" cast and crew were at the "For Your Consideration" Emmy event where it was officially announced that both actors Scott Michael Foster ("Nathaniel Plimpton III") and David Hull ("Josh Wilson") were promoted from recurring to regular cast members.
