Production
Mrs. Davis was created by Damon Lindelof and Tara Hernandez at Warner Bros. Television, and the show received a 10-episode series order for Peacock. The pair would both co-write and executive produce, with Hernandez acting as showrunner. Susan Rovner had been developing the series with them at Warner Bros., and as new chair for NBCUniversal Television and Streaming, she out-bid other broadcasters and streamers to buy the show. Owen Harris and Alethea Jones are executive producers and each directed multiple episodes.
Casting began in March 2022, starting with Betty Gilpin in the lead role of a nun battling artificial intelligence, and Jake McDorman starring opposite her. Margo Martindale, Andy McQueen, and Ben Chaplin were added to the main cast, while David Arquette and Elizabeth Marvel received recurring roles. After the start of filming, Chris Diamantopoulos, Ashley Romans, and Katja Herbers were added to the cast as well.
Filming was in progress in August 2022, shooting primarily on the Warner Bros. lot or in a remote desert location to maintain secrecy.
The international scenes were filmed in Spain: Sa Boadella beach in Lloret de Mar (Arthur Schrodinger's island), Cathedral in Girona (the execution of the Templars), Figueres Fortress (sword contest), Valencia (Shrodinger's ship in Cadiz) and Sant Pau Hospital in Barcelona (Shrodinger's university).
Writers used AI to come up with episode titles.
Teller (half of the comedy magic duo Penn & Teller) was a magic consultant for the series.
In May 2023, it was reported that there were no plans for a second season.
