“Dexter: Original Sin” Sets Cast with Golden Globe Winner Christian Slater, Patrick Gibson, and Molly Brown for Paramount+ with Showtime

Paramount+ with SHOWTIME today announced the cast of the new original drama 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 (DEXTER, NURSE JACKIE) will return as showrunner and executive producer. Taking place 15 years before viewers first met Dexter in the hit SHOWTIME® series DEXTER, this new 10-episode thriller will chronicle America’s favorite serial killer…in training.

Set in 1991 Miami, DEXTER: ORIGINAL SIN follows Dexter (Gibson) 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 (Slater), 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.

Slater received Golden Globe and Critics Choice Awards along with multiple nominations for his role in Mr. Robot. His other credits include Dr. Death, for which he received a Critics Choice nomination, Dirty John and Nymphomaniac along with cult classics True Romance and Heathers. Slater is currently starring in Jerry Seinfeld’s directorial debut, Unfrosted, and The Spiderwick Chronicles. He will next star in Zoe Kravitz’s directorial debut, Blink Twice.

Gibson can most recently be seen in the television series Shadow and Bone. Additional past credits include in The OA, Good Girl Jane, and Property of the State, the latter of which earned him the Irish Film and Television Award ® for Rising Star in 2017.

Brown’s past credits include roles in EVIL, BILLIONS, and The Marvelous Mrs. Maisel, as well as films including Senior Year and The Good House. She’s set to appear in the upcoming independent film Mooch.
