Positive Update on Second Dexter Prequel Show Featuring Trinity Killer and John Lithgow’s Return

The highly anticipated prequel series focusing on the Trinity Killer from the Dexter franchise is edging closer to realization, following recent updates. Dexter Morgan, played by Michael C. Hall, serves as a blood-spatter analyst for the Miami Metro Police Department, but he leads a double life as a vigilante who seeks out and eliminates other murderers. This new series aims to delve into the backstory of Arthur Mitchell, portrayed by John Lithgow, a character recognized as Dexter’s most formidable foe, whose infamous moniker stems from his chilling pattern of three murders, each influenced by his traumatic childhood as depicted in Season 4 of *Dexter*.

We wrote the entire Trinity Killer series. At the moment, it is on the back burner. John Lithgow has agreed to be the voice of his younger self the way Michael Hall is doing for [Original Sin]. There’s that and we’re doing another show with Michael C. Hall, [Resurrection]… We were writing that while shooting Original Sin, so that’s fairly busy. We begin shooting [Resurrection] in January and it will air in June 2025.

Viewers will be introduced to Mitchell’s harrowing backstory—featuring themes of familial loss, including the accidental death of his sister Vera, his mother’s suicide, and the trauma of an abusive childhood. Such narrative depth aims to meld horror with a thought-provoking exploration of the factors that drive individuals toward villainy, ultimately crafting a nuanced depiction of Dexter’s arch-nemesis.
