The Dexter series is growing with a new spinoff based on one of its most iconic villains, the Trinity Killer. Showrunner and executive producer Clyde Phillips has given Collider a major update on the show. The Trinity Killer, portrayed by John Lithgow, was first seen in Season 4 of the original Showtime show and soon emerged as the centerpiece of Dexter's narrative.

Lithgow is scheduled to reappear in some capacity for the upcoming series, although the timing of the show is unknown. Phillips's latest statements have given fans renewed hope and expectations about the spin-off development and launch date.


The Trinity Killer spin-off: Everything that is confirmed

As reported by Collider, Clyde Phillips has confirmed that the new spin-off will cover the Trinity Killer. This is the character of John Lithgow and is one of the most influential villains to appear in the franchise.

The spin-off will cover more of his story. Lithgow is rumored to be on board with the project, but it is not clear yet how he will be featured or which stage of the character's life the show will be covering.


Timeline and setting of the spin-off

The actual timeline of the Trinity Killer spin-off has not been determined. From Collider, the Trinity Killer operated for many decades, so the show's creators have room to decide when they want the story to take place.

In the original Dexter series, the Trinity Killer was revealed in Season 4, but his criminal life spanned many years. That leaves the spin-off freedom to use various times in his life, possibly before or following his stint in Dexter.


John Lithgow's role and involvement

John Lithgow's performance as the Trinity Killer was a huge contributor to Dexter's popularity. Lithgow is supposed to return for the new spin-off, according to Collider. What his role entails is not entirely clear. The series could do this through flashbacks, new filming, or some other device. Lithgow's return is an important aspect in creating buzz for the spin-off.


Showrunner Clyde Phillips's update

Clyde Phillips, the current showrunner of the expanded Dexter franchise, recently shared an update regarding the status of the Trinity Killer spin-off. As per Collider, Phillips' statement has made fans positive about the progress of the project. No release date has been officially confirmed, but the update indicates that work is in progress and the show is nearer to reality.


Future of the Dexter Franchise

The franchise has gone on to develop further after the original series concluded. Adding new spin-offs, such as the Trinity Killer project, demonstrates the continued desire for the narrative and its characters.

The franchise's expansion is being handled cautiously by Phillips, according to Collider, as he works to ensure new projects are of the same quality and audience appeal as the original series.


In a nutshell, John Lithgow will be returning in the new spin-off about the Trinity Killer, although the specifics of his return and the timeline of the show have not been worked out. The spin-off is continuing to develop, and fans can expect more information on the venture as it moves ahead. The ongoing success of the Dexter franchise demonstrates the enduring power of its characters and tales.
