James Gunn Defends DC Roadmap: Superman, Batman, Wonder Woman Are 'Diamonds'

James Gunn has publicly reframed his eight- to 10-year DC roadmap, calling Superman, Batman and Wonder Woman the studio's "diamond characters" while naming Krypto, John Stewart and Peacemaker as lesser-known figures the studio could "turn into diamonds." The DC Studios co-head made the comments in a series of Threads posts responding to criticism of his universe-building strategy.

Gunn's defense rests on consistency. Pointing to his own record, he wrote: "You can look at my quotes from January '23 when we started and I said we were going to do exactly what we're doing." He framed the plan as twofold from the outset. Some stories, he said, would function as standalone works — "like the Guardians movies were (which is what Clayface is)" — while others, such as "the Superman Saga," would form part of a larger narrative structure. "All that said, each piece of the larger story should work on its own with or without having to see everything else," he wrote.

What does the roadmap actually cover?

In a second post, Gunn pushed back on how his earlier statements have been read. "ALSO, some things get conflated here," he wrote. "The often cited '8 to 10 year roadmap' originally pitched wasn't only story points (although that was a part of it), but also the plan for DC as a whole, including focusing on diamond characters (Superman, Batman, WW) as well as smaller characters we could turn into diamonds (Krypto, John Stewart, Peacemaker), how we would foster filmmaker freedom & allow for multiple tones & ratings, the influences of Star Wars & George RR Martin, and so much more."

The roadmap reference dates back to 2022, when Gunn and fellow DC Studios co-head Peter Safran outlined the eight- to 10-year plan during a virtual Warner Bros. Discovery town hall. What Gunn omitted this week is any accounting of which parts of that plan have shifted since — the clarification addresses intent, not progress against it.

In a third post, Gunn struck an optimistic note: "It's exciting seeing things START to come together and all that makes me even more excited for what we have in store for everyone in Man of Tomorrow."

Standalone stories versus crossover pressure

The exchange on Saturday grew out of criticism that Gunn's films are not building toward a major crossover event — the model that previously anchored DC's theatrical strategy. Responding to a commenter who argued that Gunn does not need to lay the foundation for one fully interconnected universe, he wrote plainly: "I couldn't agree more."

He went further, framing the DCU as deliberately open-ended. "DCU is just an alternate universe; we can enter at any location or time and tell THAT story," he wrote. "I dislike the idea that individual stories aren't meaningful unless they lead to something else. People not understanding this is strange to me, because 'Star Wars' has essentially been doing this for 50 years across movies, shows, games and books, admittedly without the tonal variety."

The Star Wars comparison carries a caveat of its own, which Gunn himself supplied: the franchise has done it "without the tonal variety" he claims for the DCU. Whether audiences accept standalone DC films without a crossover horizon remains untested — Clayface and the Superman Saga will be the evidence.

Gunn's next film, "Superman: Man of Tomorrow," reaches theaters July 9, 2027. That date now functions as the deadline by which his diamond thesis, and his reading of the roadmap, will face its first full public test.
