The series finale of Dexter, in which Dexter flees Miami and ends up as a lumberjack in Oregon, was polarizing to the show's fans, according to lead actor Michael C. Hall. He said "I think the ending was 'mystifying' at best to people. 'Confounding', 'exasperating', 'frustrating' — on down the line of negative adjectives."[3] Hall had been asked by fans in the eight years since the finale aired if there would be a follow-up to the show. Original showrunner Clyde Phillips, who had left the series after season 4, saw those questions asked of Hall and over time discussed possible ways to continue Dexter as some type of redemption, but could not figure out an appropriate route. Phillips was contacted by Showtime president Gary Levine on July 1, 2019. Levine told Phillips that he felt the time was right to bring back Dexter and asked if Phillips could come up with something. Phillips wrote a preliminary script which he then shared with Hall, who loved the idea.[3]

Phillips recognized the ending had suited the time when it was broadcast, as around 2013, there were a number of real-life serial killers known to be living in Oregon and nearby states. Phillips also considered that by surrounding himself with chainsaws, Dexter was under a constant reminder about how his mother had died. As Phillips was unsure of the intent that the finale was meant to deliver, he decided to incorporate a major timeskip, nearly a decade from the end of events of the original series. Dexter has since moved to the fictional town of Iron Lake, New York and is living under a pseudonym, working in an outfitter shop selling guns for hunting and has ingratiated himself comfortably into the local community. Because of that, Phillips did not consider the miniseries as a ninth season, since there was a major discontinuity in the serialization of the story.[3] As the writing staff wrote out the ten-episode miniseries, they established how the series would end and wrote backwards from that. Phillips claimed that "The ending of this one will be stunning, shocking, surprising, unexpected. And without jinxing anything, I will say that the ending of this new season that we're doing will blow up the internet."[3]

On October 14, 2020, the Dexter revival was ordered as a limited series consisting of 10 episodes, starring Hall in his original role, with Phillips returning as showrunner.[17] On November 17, 2020, it was announced Marcos Siega would direct six of the ten episodes of the limited series as well as serving as an executive producer alongside Hall, John Goldwyn, Sara Colleton, Bill Carraro, and Scott Reynolds.[15] It premiered on November 7, 2021, on Showtime.[2]

In January 2021, Clancy Brown, Julia Jones, Alano Miller, Johnny Sequoyah, Jack Alcott, and David Magidoff joined the main cast.[18][19][20] On February 11, 2021, Jamie Chung and Oscar Wahlberg were cast in recurring roles.[21] On June 28, 2021, John Lithgow joined the cast to reprise his role as Arthur Mitchell, the Trinity Killer, in a cameo appearance.[22] On July 13, 2021, it was announced that original series regular Jennifer Carpenter would reprise her role as Dexter's sister Debra in some capacity for the limited series.[23] On August 24, 2021, it was reported that Carpenter is confirmed to reprise her role as a series regular, appearing as Dexter's "imaginary iteration of Debra".[24]

Production began in February 2021, with most of the show filmed in Shelburne Falls, Massachusetts, serving as a stand-in for Iron Lake.[3] Exterior filming had to be coordinated around the weather, as the creators wanted to have a significant amount of snow in those shots, including a local frozen lake. Interior filming at New England Studios started around July 2021 over a fifty-day period.[3][25]
