Dexter: Original Sin is slowly gathering its main cast, and we finally know who’ll play the lead role. Patrick Gibson officially joined the series as the young Dexter Morgan, while Christian Slater and Molly Brown are set to play the members of his family.

Dexter: Original Sin will be set 15 years before the original series, and it will see the young Dexter Morgan make a transition from a forensics student to an avenging serial killer. Once his bloodthirsty urges become impossible to ignore, he starts learning to channel his inner darkness.

His father Harry helps him avoid getting on law enforcement’s radar by adopting a code and only finding and killing people who deserve to be eliminated from society. He must also juggle his killing sprees with his forensics internship at the Miami Metro Police Department.

Patrick Gibson (Shadow and Bone) will lead the series as the young Dexter Morgan, while Christian Slater (Mr. Robot) is set to play his father Harry. Molly Brown (Senior Year) joined the cast as Dexter’s younger sister, Debra Morgan.

They’re replacing Michael C. Hall as Dexter, James Remar as Harry, and Jennifer Carpenter as Deb, who played these characters in the original series, which ran on Showtime for eight seasons.
