Peacemaker Season 2 (Episodes 6–8) has substantial storyline developments. In an interview with entertainment journalist Brandon Davis, James Gunn said that he is holding the next three episodes of Peacemaker Season 2--episodes 6 to 8--"close to the chest" to avoid spoilers.

James Gunn jokingly referred to the DCU journey of John Cena's Peacemaker as the Tighty-Whities Trilogy- starting with The Suicide Squad and continuing with season 2 of Chris Smith's mercenary adventures.

It took until June 2023 for Corenswet and Brosnahan to be officially cast after an exhaustive audition process. The former beat out Nicholas Hoult for the role (who would go on to portray Lex Luthor in 2025's Superman), while Brosnahan went up against the likes of Emma Mackey and Phoebe Dynevor.

"Peacemaker" Season 2, on HBO Max Thursday, confirms John Cena's R-rated superhero has a place in James Gunn's new film and TV universe of DC Comics characters.

In a recent social media post, James Gunn explained how Alan Moore and Chris Sprouse's Tom Strong helped influence DC Studios' new DCU.

This week, DC Studios co-CEO James Gunn made the surprise announcement that Superman would see its digital release on Friday, August 15 — just over a month after it launched in theaters.
