Gunn has indicated that Margot Robbie's potential return as Harley Quinn will be revealed 'down the line,' keeping fans hopeful for her involvement in future DC projects.

The upcoming Peacemaker Season 2, premiering on August 21, will explore storylines involving Harley Quinn and Bloodsport, hinting at their possible inclusion in the new DCU.

Gunn is working on a new script for a Superman-related film that will feature Superman prominently, but it is not a direct sequel to the upcoming David Corenswet film.

Following the success of the recent Superman film, Gunn expressed gratitude for audience support and emphasized the film's focus on Superman’s kindness, which resonated strongly with viewers.

While details of the 'Superman Saga' remain unclear, it is expected to include Gunn's upcoming projects and possibly a broader 'Super-Family' storyline.

Gunn has discussed potential TV spinoffs for characters like Mister Terrific and Jimmy Olsen, with series such as Lanterns scheduled for 2026.

A new Batman will be introduced in 'The Brave and the Bold,' ruling out Robert Pattinson as the current Batman, with no specific release window set yet.

Gunn clarified that some elements of 'The Suicide Squad' are still considered canon, and characters like Peacemaker will continue in the new universe.

The 'Superman Saga' includes David Corenswet as Superman in a standalone film, with Milly Alcock's Supergirl set for a follow-up film next year.

Margot Robbie has expressed her love for Harley Quinn, viewing her as a versatile, fun character, and has not publicly changed her stance on passing the role to others.

Fans speculate that Robbie's reappearance as Harley Quinn could involve reuniting with the Justice Gang or a showdown orchestrated by Gunn, though specifics remain unconfirmed.

DC Studios co-head James Gunn is actively developing the new DC universe, with a focus on a reboot called 'Chapter One: Gods & Monsters,' which includes projects like Peacemaker Season 2 and a new Superman film.
