Dexter: Original Sin Trailer Incorporates Michael C. Hall Into Prequel

The Dexter: Original Sin trailer finally offered fans a glimpse at how Michael C. Hall fits into the prequel.

Showtime released the first look of the upcoming series on Tuesday, November 27, which introduced younger versions of the original Dexter cast. It also credited Hall, 53, as the “inner voice” for Patrick Gibson‘s Dexter, who spends the entirety of the sneak peek explaining the origin for his murderous tendencies.

“You got to blend in. One wrong move, you ruin your life, your sister’s, mine,” Dexter’s dad, Harry (Christian Slater), tells him in the clip, to which the titular character responds, “This is who I am, who I need to be. Learning my code was just the beginning, bringing it to life for the first time is a whole new story.”

Hall originally played the fictional serial killer from 2006 to 2013. Original Sin is set in 1991 and is focused on Dexter’s (Gibson) transition from student to avenging serial killer and member of the Miami Metro Police Department.

With help from his father, Harry (Slater), Dexter will begin his search to find and kill people who he believes should be eliminated from society. In addition to Gibson, 29, and Slater, 54, Sarah Michelle Gellar, Patrick Dempsey, Molly Brown, James Martinez, Christina Milian, Alex Shimizu and Reno Wilson round out the cast.

Hall previously returned to TV screens as Dexter in a spinoff titled New Blood, which was released in 2021 but ended one year later. There are also plans for a second? sequel series, although it remains unclear how Hall will star as Dexter on another show since his character has died — multiple times over.

“The scripts they’ve executed are fantastic,” Hall told Entertainment Weekly in August about Dexter: Resurrection, which debuts summer 2025. “I can’t wait, like, as a fan, to watch it, and as an actor, to spend time seeing real footage of things that I’ve sort of tried to imagine for myself when I imagine what Dexter’s early days [were like].”

Hall said he was excited to have more of a reference for his character, adding, “Now I’m going to have this technicolor version of his memories to refer to. I think it will help inform my experience of whatever comes next in the other series, which I can only speak vaguely about at this point. It’s pretty heady. It’s so gratifying.”

The actor also weighed in on the future of the Dexter universe.

“I’m on the inside to a certain degree and I have a sense of what’s coming but I’m really excited,” Hall shared. “I’ve spent so much time with this character and to go back and have all the imaginative blanks filled in is going to be great.”

Dexter: Original Sin starts streaming on Paramount+ Friday, December 13, before making its cable debut on Sunday, December 15. Dexter: Resurrection will debut in summer 2025.
