‘Dexter: Original Sin’ Sets Cast with Christian Slater, Patrick Gibson, and Molly Brown

Christian Slater, Patrick Gibson, and Molly Brown

In 2023, Showtime announced it had placed a straight-to-series order for a new drama series based on a young Dexter Morgan, the lead character of the hit series “Dexter,” which starred Michael C. Hall. This week, Paramount+ with Showtime announced the cast of the series, “Dexter: Original Sin” (previously titled “Dexter: Origins”).

Patrick Gibson(“Shadow and Bone”) will play the titular role of Dexter Morgan; Golden Globe winner Christian Slater (“Mr. Robot”) will play Harry Morgan, Dexter’s adoptive father and homicide detective; and Molly Brown (“Senior Year”) will play Dexter’s younger sister, Debra Morgan. Emmy nominee Clyde Phillips will return as showrunner and executive producer. Taking place 15 years before viewers first met Dexter in the original “Dexter” series, this new 10-episode thriller will chronicle America’s favorite serial killer…in training.

Set in 1991, Miami, “Dexter: Original Sin” follows Dexter as he transitions from student to avenging serial killer. When his bloodthirsty urges can’t be ignored any longer, Dexter must learn to channel his inner darkness. With the guidance of his father, Harry, he adopts a Code designed to help him find and kill people who deserve to be eliminated from society without getting on law enforcement’s radar. This is a particular challenge for young Dexter as he begins a forensics internship at the Miami Metro Police Department.

The eight-season run of the original “Dexter” series premiered in the fall of 2006. It starred Golden Globe winner Michael C. Hall as Dexter Morgan, a complicated and conflicted blood-spatter expert with the Miami Metro Police Department who moonlights as a serial killer. The show became one of the most acclaimed series on television, earning multiple Emmy and Golden Globe nominations for best television drama series as well as a prestigious Peabody Award in 2008, and was twice named one of AFI’s top 10 television series. In 2013, the Writer’s Guild of America included “Dexter” in their “101 Best Written TV Series” list. In 2021, the original series’ sequel, “Dexter: New Blood,” delivered record-breaking numbers, becoming the most-watched series in Showtime history. All previous seasons of “Dexter” and “Dexter: New Blood” are now available to watch on demand and on streaming for Paramount+ subscribers with the Paramount+ with Showtime plan.

“Dexter: Original Sin” is executive produced by Clyde Phillips and produced by Showtime Studios and Counterpart Studios. Executive producers also include Scott Reynolds (“Jessica Jones”), Michael C. Hall (“Dexter”), Mary Leah Sutton (“Resident Evil”), Tony Hernandez (“Emily In Paris”), and Lilly Burns (“Russian Doll”), with the series being produced by Robert Lloyd Lewis (“The Lincoln Lawyer”). Reuniting with Slater is Michael Lehmann (“Heathers”), who serves as directing executive producer.

For Showtime Studios, the series is being creatively overseen by Gary Levine and Urooj Sharif, with production supervised by Tara Power. The series is distributed by Paramount Global Content Distribution outside of Paramount+ markets.
