Since directing Guardians of the Galaxy in 2014, James Gunn has become a favorite among many for his candor on social media. The filmmaker routinely hosts impromptu Q&A sessions with people who have questions, often answering many questions at once. One of those events took place Wednesday night, with the new DC Studios boss answering some questions about the upcoming DC Universe slate in a post on his Instagram.

Gunn, for example, mentioned that earlier in the week The flash would reset all things in DC, implying it will pave the way for a clean slate when the DC Universe officially kicks off next year. A fan followed that up with a clarification about the continuity of certain characters and projects. “Flash reset a lot of things, not all things,” Gunn revealed. “Some characters stay the same, some don’t.”

When does the DCU officially start?

Between now and Superman: Legacy‘s release in 2025, five film projects are scheduled for release. The will of Shazam!: Anger of the Gods, Blue Beetle, Aquarius 2and The flash whether or not in the same continuity with the rest of the DC Universe. The likes of Gunn and Peter Safran have yet to determine which projects will stay in line with everything else. That said, there will be a clear break sometime Superman: Legacy hits theatres.

“The only thing we can promise is that everything from Superman onwards, from our first project, will be canon and will be connected,” Gunn said. “We’re using some actors from the past. We’re not using any other actors from the past, but everything will be connected and consistent from there.”

Will Ezra Miller remain The Flash?

As characters like Superman and Batman get new actors within the DCU, some will return to their roles, like Viola Davis’ Amanda Waller. When it comes to Miller, it’s unclear if the actor will return, though Safran hasn’t ruled out their return.

“Ezra is fully committed to their recovery,” said Safran. “And we fully support that journey they’re on right now. When the time is right, when they feel they’re ready to have the discussion, we’ll all figure out the best way forward. But right now they’re totally focused on their recovery, and in our conversations with them over the past few months, it feels like they’re making tremendous progress.”
