The director’s Superman reboot is now available to stream with an added commentary track where he accidentally revealed a twist in his superhero spin-off series starring John Cena.

During a scene where Lex Luthor and government officials are discussing how to deal with the potential threat of Superman, Gunn said that a scene for Peacemaker was shot on the same day due to it featuring some of the cast members.

"The Saturday after we did [this Superman scene], we shot a scene from Peacemaker [season 2] episode eight, because it had a lot of the same cast from Superman," Gunn said.

"It had James [Hiroyuki Liao] as Mori and Frank [Grillo] as Rick Flag, and then a couple of other people. I think this will have already aired when this director's commentary comes out, but I'm not sure, actually – I'll leave the secrets there."

However, Gunn’s timings were off as the commentary track had been released before Peacemaker’s finale, which isn’t due to air until 9 October.

Beyond that, Gunn remained quiet about who the cameos could be. Naturally, fans will speculate that it could be David Corenswet’s Superman or Nicholas Hoult’s Lex Luthor. Other candidates are Rachel Brosnahan as Lois Lane or Edi Gathegi as Mister Terrific.

Nathan Fillon, Isabela Merced and Sean Gunn have already starred as their respective DC characters in episode one of Peacemaker’s new season. In contrast,

He confirmed the news on X/Twitter with a comic book image of image of Superman next to Luthor, who is wearing a green and purple armoured suit.

In the DC comics, Luthor designs the suit so he can battle Superman – though it has never been re-created in live-action form.

Superman earned more than $611m (£453m) at the worldwide box office following its July release, making it the highest-grossing superhero film of the year.
