DEXTER Prequel Series About John Lithgow's "Trinity Killer" Moving Forward With Clyde Phillips & Scott Reynolds as Co-Creators

by · GeekTyrant

The Dexter prequel series following the origins of the notorious serial Trinity Killer, played by John Lithgow in the mothership series, remains “in development” at Paramount+ with Showtime. Original Dexter showrunner Clyde Phillips and fellow Dexter veteran Scott Reynolds will serve as co-creators and executive producers of the spinoff prequel series.

Despite rumors the show had halted, sources said they held a development room for the project earlier this spring. Scripts have been written, and Phillips shared an update on the Trinity Killer offshoot with Deadline while promoting Dexter: Original Sin in New York City earlier this month.

“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.”

Showtime and Phillips’ focus has been on Original Sin, which premiered December 13, with Resurrection, the continuation of the highly-rated limited series Dexter: New Blood, also as top priority. Resurrection, which will be narrated by Patrick Gibson who plays Young Dexter in Original Sin, was soft-launched in the Original Sin premiere which revealed Dexter survived the shooting that was meant to kill him for good by his son Harrison (Jack Alcott) at Dexter’s request.

The network and studio executives are also likely waiting to see how Original Sin does to gauge if there is appetite for a further Dexter universe expansion before committing to Trinity. So far, things are looking promising as the series premiere of Dexter: Original Sin racked up 2.1M global viewers across Paramount+ and Showtime in the first three days of availability, according to Paramount Global. The company also says it is Showtime’s most-streamed premiere ever, although it didn’t specify how much of that audience came from streaming.
