On January 8, 2017, The CW renewed the series for a fourth season. It was later announced on May 18, 2017, that the series had been moved from its Monday night time-slot to a Friday night time-slot, being paired alongside the third season of
Crazy Ex-Girlfriend, premiering on October 13, 2017. The last seven episodes of the season were paired alongside
Dynasty, which was moved from Wednesday night to Friday night in the middle of the broadcast season. The season also received a reduced episode account, per request of showrunner
Jennie Snyder Urman, bringing the season's episode count to a total of 17, making it the shortest season of the series in total. When the promotional poster for the season was first released, it was revealed that the character of Mateo was recast with Elias Janssen due to previous
child actor Joseph Sanders being too busy with school to commit to the role. As of the first episode of the season, Janssen was credited with "starring" billing along with the six other series regulars. On September 20, 2017, it was announced that
Alex Meneses was set to recur as Katherine, "owner of the Cortes Hotel Conglomerate, who is a possible investor of Rafael (
Justin Baldoni) and Petra's (
Yael Grobglas) hotel". On January 7, 2018, it was announced that
Rosario Dawson joined the cast for a multi-episode role in the back-half of the season, though the details of her role remained kept under wraps until the character's introduction scene was released a day before her debut episode was set to air, revealing that Dawson would be playing Jane Ramos, an attorney hired to defend Petra. The back-half of the season also saw
Brooke Shields in a multi-episode arc as River Fields, Rogelio's (
Jaime Camil) nemesis and a spoof of the real-life actress. On January 9, 2018, series star
Gina Rodriguez announced via
Instagram that she would be making her directorial debut this season, posting a photo of herself holding a
Jane the Virgin clapperboard with her name next to the director slot, alongside costars Yael Grobglas and Rosario Dawson. Rodriguez's directorial debut was the tenth episode of the season, "Chapter Seventy-Four", which aired on February 9, 2018. The episode was specially selected by showrunner Jennie Snyder-Urman as it featured the characters of Jane (Gina Rodriguez) and Rafael (Justin Baldoni) having sex for the first time. "She said that it would be really great for me to be able to direct something that is so intimate and could be very uncomfortable. It could be very scary to not only shoot, but also to be in that environment...So there were a lot of layers of challenge and then it ended up being so beautiful," Rodriguez recalls of her directing experience. Costar Justin Baldoni also directs this season, taking on the fourteenth episode, "Chapter Seventy-Eight". ==Cast and characters==
