Following the chilling new teaser for Showtime's upcoming revival of Dexter, an intriguing nugget of information has now emerged, with actor James Remar revealing that he will not return as the serial killer's late father and guiding subconscious, Harry Morgan. The back and forth between Harry and his murderous son provided the original run with some of the show's most interesting and dramatic moments, but it sounds like they will not be making a comeback this time around.

"They didn't ask any of the original cast back, so I don't know what they're doing...I really have no idea. It's too bad because all of us wanted to go back. But, you know, it's their show, so they're gonna do what they wanna do."

While some details regarding the new series have been revealed, none of the original cast members have been confirmed aside from Michael C. Hall as the titular lead. While Remar claims that none of the original cast have been asked to return, a recent social media post from star Jennifer Carpenter may have at least confirmed the return of Dexter's sister Debra. While nothing has been confirmed, the image shows the actress on the set of a new project, and the timing certainly checks out, with the Dexter revival currently filming in Massachusetts.

While Debra met her end during the much-maligned series finale, the image shared by the actress has led many fans to believe that she will take over from Harry as Dexter's inner-voice, and theory that has now been backed up somewhat by the fact that Remar will not return.

Showtime surprised Dexter fans everywhere when they announced last year that the charming serial killer would return for a 10-episode limited series, with original showrunner, Clyde Phillips, back at the helm. Michal C. Hall will reprise the title role and is set to be joined by a host of new characters, including Clancy Brown as the central villain Kurt Caldwell, the unofficial mayor of the small town of Iron Lake. Described as powerful, generous, loved by everyone and a true man of the people, you should never make the mistake of crossing Kurt, or hurting anyone that he cares for, or he will make you pay.

Jamie Chung (Lovecraft Country), Julia Jones (Goliath, The Mandalorian), David Magidoff (The Morning Show) and Alano Miller (Jane the Virgin) have also joined the series and will provide Halls' Dexter Morgan with all manner of drama and, no doubt, people to kill.

Dexter has become infamous for its disappointing finale, which saw the character abandon his family to live in self-imposed exile, growing out a scruffy beard and living life as a solitary lumberjack. Fans have been hoping for some time that Dexter would return to make amends, with the new season set to pick up with Dexter still living alone in upstate New York.

Hall recently explained why now was the right time to bring Dexter back saying, "This one, a lot of it has to do with time passed. This is going to happen in real time, as if as much time has passed since the finale happened," the actor revealed recently. "And yeah, we kind of just got the creative band back together again. Clyde Phillips is back, who was the showrunner for the first four seasons, running the show. And Marcos Siega, who is one of the directors. We're gonna shoot it like a long, 10-hour movie. It was a combination of the scripts and the timing. I always thought maybe the time will reveal itself when it's the right time to do it and it did. And I'm excited."

Production on the Dexter revival began in February 2021, with a fall 2021 premiere date scheduled. Remar's comments were posted to Reddit by user thekraken_1.
