Development Dynasty was renewed for a third season on January 31, 2019. In May 2019,
Deadline Hollywood reported that co-executive producer Josh Reims would succeed co-creator
Sallie Patrick as executive producer and showrunner for season three. On January 7, 2020,
Dynasty was renewed for a fourth season.
Casting In July 2019, it was announced that
Ana Brenda Contreras would not be returning for season three for personal reasons, and that
Daniella Alonso would take over the role of Cristal. In August 2019, it was reported that
Michael Michele had been promoted to a series regular for the third season, and it was announced in October 2019 that
Adam Huber had been promoted to a series regular as well.
Kelli Barrett and
Jade Payton also joined the show in recurring roles, Barrett acting as Adam's nurse, Nadia, and Payton portraying Dominique's stepdaughter, Vanessa. On October 28, 2019, it was announced that the role of
Alexis Carrington had been recast with
Elaine Hendrix, who would appear as a series regular. The CW noted that "Alexis is back in Atlanta, with a new look, a new man, and plenty of scores to settle". In February 2020, it was announced that
Wil Traval had been cast to recur as Father Caleb Collins, a "young, charming and irreverent priest with a soft spot for the disabled vets who rehab in the hospital's clinic." He was teased as a potential love interest for Cristal.
Danny Trejo appeared as himself in the May 2020 episode "
Robin Hood Rescues".
Filming Production of
Dynasty was suspended in March 2020 as a direct result of the
COVID-19 pandemic. Filming of only 20 of the 22 ordered episodes of the third season had been completed at that time. Gillies said, "So there is no finale at this juncture, and there is no episode before the finale. So it ends in a very weird place ... I don't know if we'll pick up the finale later, I’m not sure what the plan is. It certainly shouldn't end on the episode we finished, because it's just really random and nothing’s resolved. I apologize if it does." It was later confirmed that the 20th episode of the season, "
My Hangover's Arrived", would serve as the season finale, though it has not been announced whether the remaining two episodes of the season will be produced later. Hoping to use reworked versions of the two scripts to start the fourth season, Reims teased Blake going to war with Alexis, Jeff and Adam; Sam's new relationship with Ryan; and the return of the Moldavians. ==Broadcast==
