‘Dexter: Original Sin’ will present serial killer’s origin story

The “Dexter” franchise is coming back again, this time without Michael C. Hall. The murdering vigilante first returned in the 2021 limited spinoff series “Dexter: New Blood,” which focused on him and his son. Now the character will return in a prequel called “Dexter: Original Sin,” which will tell his backstory, much of which we heard about in the first series.

The Showtime-Paramount+ series will be set in 1991 Miami, and young Dexter will be played by Patrick Gibson, from “Shadow and Bone” and “The OA.” We’ll see him go from student to serial killer, with guidance from his father, homicide detective Harry, who will be played by Christian Slater (he was played by James Remar in flashbacks in the original series). Molly Brown, from the movie “Senior Year,” has been cast as Dexter’s sister, Debra.
