James Gunn Confirms Superman Sequel: Script in Progress, Production to Start Soon

DC Studios is wasting no time continuing the Superman legacy. Just weeks after Superman soared into theaters, DC Universe creative head James Gunn has officially confirmed that a sequel is already deep in development, marking a bold new chapter in the revitalized franchise.

In a recent interview published August 18, 2025, Gunn revealed that not only is the Superman sequel scheduled, but the treatment — a detailed 60-page outline — is already finished. The follow-up promises to expand on the “Superman Saga,” a narrative arc at the heart of the DCU’s Chapter One: Gods and Monsters.

Gunn’s announcement comes on the heels of the theatrical debut of Superman, starring David Corenswet as Clark Kent. The reboot follows Kent’s struggle to balance his life as a journalist and a superhero, while facing off against the notorious Lex Luthor and a public questioning his loyalty to Earth.

What Is the Latest Update on James Gunn’s Superman Sequel?

James Gunn has officially completed the treatment for the next Superman film and is now transitioning into the full scripting phase. Known for his meticulous storytelling, Gunn’s treatments aren’t mere outlines — they’re fully fleshed out with dialogue and complex narrative structures.

“I’m totally done with the treatment,” Gunn stated. “My treatments are incredibly intense. They’re 60-page treatments with dialogue and everything.”

He added that the team is actively scheduling production and expects to begin filming much sooner than fans might anticipate. This sequel isn’t just another installment — it’s a key component in the unfolding DCU storyline.

Why the Superman Sequel Is Central to the New DC Universe

According to Gunn, this sequel will continue the evolving “Superman Saga” and play an integral role in shaping the broader Gods and Monsters chapter of the DCU relaunch. This saga will tie together various DC projects under one cohesive vision, with Superman leading the charge.

This approach signals a distinct move away from fragmented DC storytelling of the past. Instead, the studio is focused on weaving a unified cinematic universe — and Superman’s journey is at its core.

Gunn also hinted at connections between the Superman sequel and other upcoming DC projects, particularly Peacemaker Season 2, where Superman is set to play a “big part.”

“We have the setting up of all the rest of the DCU in this season of Peacemaker,” Gunn explained. “Lots of characters that we’ve already met in Superman will show up again. It’s incredibly important.”

David Corenswet’s Superman Ushers in a New Era

David Corenswet’s portrayal of Superman has received praise for blending classic charm with a modern emotional depth. His version of Clark Kent embodies moral conflict, public skepticism, and inner strength, setting the stage for more grounded storytelling.

While specific plot details of the sequel remain under wraps, industry watchers expect deeper exploration into Superman’s role as both an alien protector and a human symbol. With Lex Luthor still in the shadows, the stage is set for more psychological and ideological confrontations.

Expert Analysis: What This Means for the DCU’s Future

Film analysts view Gunn’s early announcement as a strategic move to maintain momentum following Superman’s box office success. By confirming the sequel and its place in the larger DCU, Warner Bros. is assuring fans that a long-term vision is finally in motion.

The fact that production is being scheduled so quickly suggests high confidence from Warner Bros. Discovery in both the franchise and Gunn’s leadership.

More importantly, the transparency around the writing process offers fans a rare glimpse behind the scenes, building trust and anticipation.

What’s Next for Superman and the DC Universe?

If filming begins as scheduled, the Superman sequel could hit theaters as early as 2027. Meanwhile, Peacemaker Season 2 will act as a connective thread between Superman and the rest of the DCU, helping to establish crossover characters and storylines.

Fans can expect more updates in the coming months, especially as the script nears completion and casting decisions surface.

James Gunn’s Superman sequel is shaping up to be more than just a continuation — it’s the centerpiece of a carefully crafted cinematic universe. With scripting already underway and production on the horizon, DC fans have plenty to look forward to as the saga unfolds.
