James Gunn, DC Studios co-CEO, has confirmed that Peacemaker will definitely happen, despite it not being included in the first half of the DCU’s film and TV slate for Chapter 1: Gods and Monsters. This suggests Peacemaker will be a part of the second half.

Gunn announced this update via his Twitter account in response to a fan who asked if the sequel was canceled. According to the producer, Peacemaker season 2 is still in the works, although it has been pushed back for other projects that are set to release before the sequel.
In his words, "Heck no, just postponed while I work on [Superman:] Legacy. Waller first. [Peacemaker] after."
Heck no, just postponed while I work on Legacy. Waller first. PM after.

Following Peacemaker’s successful run on HBO Max, it was renewed for a second season. Not long after, while wishing one of the show’s characters a happy birthday, Gunn hinted that the show’s second season would start shooting soon. However, it appears plans have since changed, especially since the show wasn’t announced as part of Gunn and Safran’s near plan for the rebranded DCU.
Set in the aftermath of The Suicide Squad, Peacemaker follows an aggressively patriotic hitman named Christopher Smith who believes that peace must be achieved, irrespective of the cost. After his performance with The Suicide Squad, Amanda Waller retained him and forced him to team up with another ARGUS black ops squad tagged Project Butterfly, which is tasked with locating and eliminating parasitic butterfly-like creatures around the world.
Apart from John Cena, who starred as the titular character, Viola Davis also reprised her role from The Suicide Squad. The show also featured Danielle Brooks, Freddie Stroma, Clemson Mum, Jennifer Holland, Steve Agee, and Robert Patrick.
Created for television by James Gunn, the show is a standalone spin-off of 2021’s The Suicide Squad and the first television series in the DC Extended Universe. Gunn developed the show’s script and also served as executive producer alongside Peter Safran, and Matt Miller, while Lars Winther, John J. Starke, and John Rickard served as producers.
By the way, Waller, based on Viola Davis’s character of the same name from The Suicide Squad and Peacemaker season 1, is part of the DCU’s Chapter 1: Gods and Monsters TV slate.
According to Gunn’s previous comments, the show will pick up after the events of Peacemaker and bridge the gap between it and the show's second season. He further noted that the series will include a few characters from Peacemaker as regulars and also comprise a highly creative production team, including Doom Patrol creator, Jeremy Carver, and Watchmen co-writer, Christal Henry.
While Gunn’s tweet confirms that Peacemaker season 2 will still happen, his confirmation of its postponement means it will take some time to arrive. At the moment, there is no information on the show’s release date, cast, crew, and plot. However, as the studio moves ahead with its content plan for the near future, more information should come to light on the show.
In the meantime, Peacemaker season 1 is available on HBO Max.
