Who knew that a show about a vigilante serial killer would have this much longevity? The original Dexter first premiered on SHOWTIME in 2006 and ran for eight seasons, and was rebooted for the limited series Dexter: New Blood in 2021. This week, the Dexterverse is expanding once again with the prequel series Dexter: Original Sin which premieres Friday, Dec. 13 on Paramount+ with SHOWTIME. On the new series, Patrick Gibson will portray a young Dexter Morgan as he begins his forensics internship at the Miami Metro Police Department and soon develops a thirst for killing. Christian Slater stars as his father, Harry Morgan.
Along with Gibson and Slater, the cast includes Patrick Dempsey, Molly Brown, James Martinez, Christina Milian, and Sarah Michelle Gellar. Michael C. Hall, who originated the role, returns to voice the inner monologue in Dexter Morgan’s head.
