James Gunn Announces The SUPERMAN SAGA: "I've Already Completed A Treatment For The Next Story"

The premiere of Peacemaker season 2 is currently underway in LA, and James Gunn shared an update on the next chapter in what he refers to as the "Superman Saga" while being interviewed by THR on the red carpet.

Whether this corner of the DCU is now officially known as the Superman Saga is not clear.

The trades have already confirmed that Gunn is working on some sort of Superman sequel (it's previously been described as being part of the "Superman Family"), and the filmmaker has now revealed that he has already completed a treatment for the project and hopes to see it enter production fairly soon.

We still don't know much about this movie, but there's a lot of speculation that it might end up focusing on the Man of Steel (David Corenswet) teaming up with Supergirl (Milly Alcock) and Krypto to face-off against Brainiac, and/or possibly The Authority.

“It’s a big part, definitely Superman leads directly into Peacemaker; it should be noted that this is for adults, not for children, but Superman leads into this show and then we have the setting up of all of the rest of the DCU in this season of Peacemaker, it’s incredibly important,” Gunn added. “Lots of guest stars coming up, lots of characters that are showing up that we’ve already met in Superman. I don’t think there’s anything that I’ve ever done that I love more than this season of Peacemaker, so I’m so excited for people to see it.”

Gunn also shared an update on Waller, which is still moving forward despite a few setbacks.

Superman stars David Corenswet as Clark Kent/the Man of Steel, Rachel Brosnahan as Lois Lane, Nicholas Hoult as Lex Luthor, Isabela Merced as Hawkgirl, Nathan Fillion as Guy Gardner, Edi Gathegi as Mr. Terrific, and Anthony Carrigan as Metamorpho.

The cast also Pruitt Taylor Vince and Neva Howell as "Ma" and "Pa" Kent, and Milly Alcock's Supergirl has been confirmed to make her debut ahead of her own Woman of Tomorrow movie.

"And that’s a wrap," Gunn posted last year when filming concluded. "God bless our cast and crew whose commitment, creativity, and hard work have brought this project to life. I set out to make a movie about a good man in a world that isn’t always so much. And the goodness and kindness and love I’ve encountered on a daily basis on the set has inspired me and thrust me forward when I felt too spent to move on my own.

Thank you all from the bottom of my heart. It has been an honor. The destination has been Superman, but the journey has been the toil and the laughter and the emotions and ideas and magic we’ve shared together on set - and for that I am forever grateful."

You can check out a synopsis for the movie below.

"In his signature style, James Gunn takes on the original superhero in the newly imagined DC universe with a singular blend of epic action, humor and heart, delivering a Superman who’s driven by compassion and an inherent belief in the goodness of humankind."

A DC universe where Bataman is not the central character sounds nice

Let’s actually leave the negativity at home for this one. Let’s be happy there is some focus on Superman and this DCU.

@Thebronxknight - Agreed! The DCEU tried a couple of times and then put Superman on a shelf for years. This is reason to be happy.

@Thebronxknight - agreed. As another cinematic ‘renaissance superman’ once said…

I’m totally down for Superman to team up with Supergirl to take on Brainiac, but if Krypto helps take him down, it’s kinda going lessen him as a villain.

Krypto is rarely used in the comics, but in Superman he was like a co-star!

@Huskers - Well this goofy Superman needs sidekicks so you know Krypto will end up being the true hero.

@Huskers - Not if it's Krypto and it's believable. Krypto taking down Lex was pitch perfect. I think it's more likely that Brainiac is going to hurt Krypto, which will set off Kara to find another gear.

need to introduce henshaw and the eradicator in these next projects to set the stage for a live action Reign of the Supermen! We don't care about the battle with Doomsday, that could be glossed over, done too many times, but the story potential of the 4 supermen battling over 2 or 3 movies, with green lantern coming in at the end for the battle with Mongol and Henshaw would be absolutely epic. They always get to the death of superman, and then skip what was one of the greatest comic book stories ever told.

@woderwick - 100%. But I’ll suggest that death of Superman be a JL movie (the DC heavy hitters did show up to help in the comics) maybe the second JL movie, and they could do reign as a series of varied projects - animation, shows then the Superman solo movie after that is him returning.

@woderwick - We could just NOT do the death of Superman. It's old hat and he's not Jesus.

A tv show getting an LA premier is new to me. If Superman flopped, this is cost they cannot spend imo. So does it mean... 🤔

But happy to be lectured, im not into showbusiness anyway, lolz!

And I think this is one of the reasons they are rushing Superman on digital inspite of it still doing good in theaters.

Im guessing there are plans for an uncut version in cinemas of Superman soon as well

Come up with your own film terms. Why he jacking Matt Reeves The Batman crime saga? I bet Gunn envy’s Matt Reeves. I do respect his sense of urgency to put more Superman material out and not sit around waitin on other characters. Pisses me off Batman is nowhere to found and Gunn saying he doesn’t know about Flash, WW and Aquaman etc. clearly shows he’s winging it. And his Gods and Monsters phase is not what’s planned. He should just shut up and give us what we want.

I'm interested in who could play BRAINIAC (if the rumors are true). I like Mads Mikkelsen for this.

Interesting…

This makes me believe even moreso that we are getting a Superman & Supergirl team up film (with Krypto) against hopefully Brainiac.

If that’s the case then I hope this version if Brainiac has a connection to Krypton such as maybe he destroyed & took the bottle city of Kandor…

Kara finding this out wants revenge and to restore Kandor but Clark given his experience with his parents maybe briefly thinks they may not be worth saving which causes friction with Kara which gets worse as they already don’t get along much it seems but ultimately Kara makes him realize that not all Kryptonians were like his parents which causes the cousins to grow closer as they take out Brainiac.

That’s obviously a rough outline but I think could potentially be a good story though we’ll see.

I can see the appeal of having the new DCU revolve around Superman over Batman. It makes sense, it’s basically what the comics do anyway. But if Gunn is putting the DCU Batman on hold until Reeves finishes his else worlds story, that is a huge disappointment and a big disservice to Batman fans and DC fans in general. Because, although they may have been too much of a focus on Batman in years prior, he is still one of the main characters of the DCU, and waiting too long to develop him and his entire BatFamily is a huge mistake as it’ll take years to introduce everyone anyway.

Fact is there are too many DCU Characters for Gunn to slow drop them in, and at this rate the timing just isn’t going to work unless these actors are signing multi year contracts, closer to decade long contracts.

@MuadDib - i dont think he is putting the dcu batman on hold. All of these films will lead to a justi e league being formed so the dcu batman is crucial to it and will not afford being delayed
