James Gunn Shuts Down Three DC Rumors: Batman, Supergirl, Man of Tomorrow

James Gunn says three DC Studios rumors going around this week are false: Matt Reeves is not leaving The Batman Part II, Milly Alcock has not been fired as Supergirl, and Man of Tomorrow did not bomb a test screening. Gunn, who runs DC Studios with Peter Safran, replied to a fan on Threads on Friday, October 16, 2026, writing that people “just have to stop listening to BS,” according to Comic Book Co and CinemaBlend.

Quick answer: All three rumors are denied by Gunn himself. Reeves had also said publicly that he is staying on The Batman Part II. Gunn says no Man of Tomorrow test screening has happened.

• Official (Gunn, Threads, Oct 16): Reeves not leaving, Alcock not fired, Man of Tomorrow did not bomb a test screening.
• Reported by Comic Book Co: the Reeves rumor started after Steven Soderbergh helped shoot part of the film while Reeves handled a personal matter; Reeves addressed it himself on X before Gunn posted.
• Reported by Comic Book Co: the Alcock rumor started after she removed Supergirl posts from her Instagram.
• Unconfirmed: timing of Gunn’s first Man of Tomorrow director’s cut. Outlets differ on how early it is, so we are not citing a figure.

What exactly did James Gunn say about the DC rumors?

A fan, tired of tracking rumor after rumor, asked Gunn on Threads whether any of three claims were true. Gunn’s answer, per CinemaBlend: “You guys just have to stop listening to BS, and I’m mostly done shooting down rumors as there are so many and I’m not on here much.” Per Comic Book Co, he denied each of the three claims and added that he was showing Safran his first Man of Tomorrow director’s cut that same day.

Is Matt Reeves leaving The Batman Part II?

No, according to Gunn and to Reeves himself. Comic Book Co reports the rumor grew out of word that Steven Soderbergh was helping shoot part of the film while Reeves dealt with a personal matter, and that Reeves had already said on X he was not leaving the project. GeekTyrant adds that the production has had real complications, but nothing suggests Reeves is abandoning the movie.

Is Milly Alcock still Supergirl?

Gunn says she was not fired. The speculation began, per Comic Book Co, after Alcock deleted Supergirl posts from her Instagram, and GeekTyrant says it picked up after the film’s disappointing box office. Deleting posts is not a casting decision, and neither outlet reports any studio statement about her future beyond Gunn’s denial.

Did Man of Tomorrow have a bad test screening?

Gunn says no test screening has happened. The rumor claimed a major character’s death hurt the reaction. If there has been no screening, there is no reaction to leak, which is why this one is the easiest to dismiss.

What this means for DC fans

Treat anonymous DC “scoop” posts with caution this season. Check whether a claim comes from a named outlet, an on-record source or Gunn and Safran directly, and look for the same detail in more than one reputable trade. When the claim names a specific test screening or a firing, ask who would know and why they would say it publicly. Gunn has said he will not keep answering every rumor, so silence from him is not confirmation of anything.

Timeline

• Thursday, October 15: Alcock’s Instagram post removals spark Supergirl speculation, per Comic Book Co.
• Friday, October 16: Gunn denies all three rumors on Threads.
• October 17-19: CinemaBlend, Comic Book Co and GeekTyrant report on the denial.

Analysis: Gunn’s reply shows how fast a single social post and a personnel detail, Soderbergh stepping in or an Instagram cleanup, can harden into a headline. A direct denial from the person running the studio is the strongest evidence available short of a release. Related: our Clayface release date and cast guide.
