James Gunn’s Superman Movie Sets Up HBO Max’s Peacemaker Season 2

Maybe you missed it, but at San Diego Comic Con 2025, James Gunn spilled some details about how his Superman movie connects to Peacemaker season 2 on HBO Max. Gunn, the mastermind behind both projects, gave us a sneak peek into how the Man of Steel sets the stage for the next chapter in the Peacemaker saga.

For those unfamiliar, Peacemaker season 2 picks up where the story of the violent antihero, first seen in Gunn’s The Suicide Squad, left off. Set to premiere just about a month after the release of Superman, the new season continues the action in both our world and the DC Universe. Gunn confirmed that Peacemaker season 2 takes place roughly a month after the events of Superman, creating a seamless transition for fans.

During the Hall H panel, Gunn also hinted at some familiar faces joining the Peacemaker cast. Characters like Guy Gardner, Hawkgirl, and Maxwell Lord are already confirmed, with the possibility of more surprise appearances. Gunn’s enthusiasm for having Nathan Fillion reprise his role as Green Lantern Guy Gardner and working with Isabella Merced, who plays Hawkgirl, was palpable. Could there be even more Superman characters making their way into Peacemaker season 2? Gunn’s cryptic comments have fans buzzing with excitement, speculating about who else might show up.
