PEACEMAKER's "Really, Really, Really Big Cameo" May Have Been Spoiled; James Gunn Clarifies DCU Canon

A new photo from the set of Peacemaker season 2 has potentially spoiled one of the huge cameos that filmmaker James Gunn has teased for the final few episodes. We also have another update on DCU "canon."

We're now a few episodes into Peacemaker season 2. While last night's episode featured some fun surprises, comments from filmmaker James Gunn have indicated that it's the final three chapters which will be responsible for blowing the minds of fans.

The DC Studios co-CEO has also said that Peacemaker is a direct sequel to Superman and a prequel to Man of Tomorrow. However, with nothing in the first five instalments sent to critics to suggest that's the case, many fans are hoping that Gunn isn't exaggerating.

He's previously said the series will include a "really, really, really big cameo," and Superman star David Corenswet may have just let the ~~cat~~ Krypto out of the bag.

The actor has shared a photo of himself in full costume as Superman, standing alongside John Cena as Chris Smith on the set of Peacemaker season 2. The shirt is from last night's episode, and the two DCU projects were filming around the same time, but this definitely seems like it could be teasing a meeting between these characters (remember, Peacemaker is rumoured to appear in Man of Tomorrow).

Superman was shown in shadow in Peacemaker's "Previously in the DCU" recap, so we'll see what happens in the weeks ahead.

Gunn's approach to building the DCU has created a lot of confusion when it comes to "canon." Well, the DC Studios co-CEO has today confirmed that "nothing is canon outside of the filmed media," including the recent Superman: Welcome to Metropolis prequel novel.

Peacemaker season 2 follows Chris Smith, the vigilante superhero, as he struggles to reconcile his past with his newfound sense of purpose while continuing to kick righteous evildoer butt in his misguided quest for peace at any cost. He discovers an alternate world where life is everything he wishes it could be. But this discovery also forces him to face his traumatic past and take the future into his own hands.

Season 2 stars John Cena, Danielle Brooks, Freddie Stroma, Jennifer Holland, Steve Agee, Frank Grillo, Sol Rodríguez, David Denman, Brey Noelle, and Tim Meadows.

James Gunn wrote all eight episodes of Peacemaker and directed three, including the first episode. Gunn, Peter Safran, and Cena serve as executive producers. Greg Mottola, Peter Sollett, and Alethea Jones also direct.

In our review of Peacemaker season 2, we wrote, "Peacemaker season 2 feels like a wholly superfluous addition to the new DCU, and lacks the stakes and emotion that made season 1 so special. Fortunately, it’s buoyed by some fun surprises for fans and another exceptional turn from John Cena."

Three episodes of Peacemaker season 2 are now streaming on HBO Max.

I really hate that Peacemaker of all characters is the posterboy for the DCU.

Laridian - 9/5/2025, 12:04 PM

@Super12 - I love hearing about what you really hate. It makes my day.

BackwardGalaxy - 9/5/2025, 1:23 PM

@Super12 - Yeah that's why the first major motion picture release was PEACEMAKER.

Wait...

Corenswet is very obviously the poster boy.

0bstreperous - 9/5/2025, 11:43 AM

But why?

Ha1frican - 9/5/2025, 11:44 AM

Well we already knew they overlapped filming bc of the The Peacemaker podcast they said they were on the set of Superman and were introduced to David

Ha1frican - 9/5/2025, 11:46 AM

My biggest hope cameo is actually GI Robot. I think there’s something off about the 2nd dimension where they are all going to be Nazis or something and that’s why Auggie is so rich and happy, if they end up invading the main timeline it would be cool to see Rick Flag pull him out of Belle Reve to help take on the dopplegangers

JoeInTheBox - 9/5/2025, 11:53 AM

@Ha1frican - Unless, I'm mistaken, I didn't see any non-white people at all in the alt-dimension. I totally think they're going to drop a bombshell that this planet is Earth-X or something similar.

tRuckRogers46A - 9/5/2025, 12:32 PM

@Ha1frican - yeah, something's definitely not right with the alt uni. Bet PM doesn't have any friends nor Eagly.
You might be onto something with the Nazi thing. Maybe they're all white supremacists. We've not seen ANY of the other 11th street kids yet either.
If White S reigns then there's the reason Keith is still alive too as Auggie wouldn't have made them fight.

Ha1frican - 9/5/2025, 12:55 PM

@JoeInTheBox - Me and my girlfriend noticed that too after the second episode too. Which is especially odd given how diverse James Gunns productions tend to be

TheVisionary25 - 9/5/2025, 11:52 AM

I certainly expect Corenswet’s Superman to be the cameo that Gunn is talking about but it could also be David just sharing a fun BTS picture since both the movie and Peacemaker S2 were being filmed somewhat simultaneously.

Also I don’t get why people can’t wrap their heads around the canon thing since James had previously mentioned that anything in regards to the previous continuity that will be mentioned or shown on screen is canon…

So something Rick Flag Jr dating June Moone/Enchantress has happened in this universe but whether it was exactly as we saw it happen in 2016’s Suicide Squad or if that film even happened is up in the air.

Yes , it’s cherry picking but that’s how he’s doing it so get over it!!.

MonkeyBot - 9/5/2025, 11:55 AM

Peacemaker and Superman were shot right next to eachother so this could also be a photo taken during a lunchbreak or something.

Ojeet78 - 9/5/2025, 12:03 PM

As much as I like Gunn and his passion for the DCU, I really am struggling to reconcile that Peacemaker and Superman are in the same universe. Superman is kid friendly and Peacemaker is way too profane to the point of gratuitous. I think there has to be some restraint. I can buy The Suicide Squad being a part of the DCU but Peacemaker is too much. The constant swearing ,nudity really serves no purpose. Both projects by themselves are fine but Gunn constantly trying to link them together is a bit off putting. Maybe, its something I'll have to get used to but I'm really wondering how it helps the brand.
It's like telling kids to read up on DC Black Label comics to catch up on what's happening in Superman Family Adventures.

Laridian - 9/5/2025, 12:07 PM

@Ojeet78 - Not really. It's called being a parent. Just because your kid enjoyed 'SUPERMAN' doesn't mean they get to watch EVERY project tied to it. Some things can just be for adults.

Ojeet78 - 9/5/2025, 12:36 PM

@Laridian - Well, tell that to Gunn. He put Superman on digital early cause he wanted it to line up with Peacemaker's release. I am perfectly fine with both projects being their own thing. I don't like the constant insistence that one is extremely important for the other.

AwesomePromoz - 9/5/2025, 12:55 PM

@Ojeet78 - Gunn doesn’t have kids and only you are responsible for yours. DC stuff hasn’t been for kids since the late 80s.

TheVisionary25 - 9/5/2025, 12:59 PM

@Ojeet78 - I feel like comics tend to be the same way tbh since one might be more adult then the other , it just offers storytelling variety imo which I’m all for!!

I do understand your hesitation though of them being apparently so linked since Peacemaker is definitely not for kids so it having an affect on on each other I can understand people not being comfortable with.

tRuckRogers46A - 9/5/2025, 12:38 PM

Doubt very much that this is the big cameo. Cant see PM wearing the same outfit for the next 3-5 episodes.
As others have said, most likely filming at the same time and just a cheeky BTS pic.

lazlodaytona - 9/5/2025, 12:40 PM

Trying to copy what Cavill and the Rock did.

I'm also not a Peacemaker fan btw.

MisterBones - 9/5/2025, 12:46 PM

Earth X Nazi universe

MuadDib - 9/5/2025, 12:53 PM

I enjoyed the recent Peacemaker episode, wasn’t as raunchy as some previous episodes, but I liked the action heavy scene with the terrorists.

I’m not a Gunn hater, and can appreciate the variety that is being offered to fans. If you want a family oriented movie, Superman is there to fill that spot. If you want more adult oriented content, with graphic violence and some nudity, Peacemaker fills the niche. I’m sure Batman will be very different whenever they get around to that. Similarly Wonder Woman will be different as will properties like Lanterns.

That each corner of the shared universe offers a different stylistic approach with varying degrees of action and comedy should be welcomed.

Not everyone wants the same thing over and over, that’s what’s lead to the somewhat stale response to the recent MCU films.

AwesomePromoz - 9/5/2025, 12:56 PM

@MuadDib - How is superman a family film? Lex Luther shoots a guy on screen in cold blood.

OrgasmicPotatoe - 9/5/2025, 12:55 PM

It's gonna be Viola Davis as Amanda Waller.

This isn't a proper DCU, it's just the Bizarro version of the DCEU. A cheap, dumber, duller copy of the original.

AwesomePromoz - 9/5/2025, 12:58 PM

@OrgasmicPotatoe - Youre a joke. Everything about the new DCU is more colourful, dynamic and entertaining.

OrgasmicPotatoe - 9/5/2025, 1:02 PM

@AwesomePromoz - I'm sorry you're so easily entertained by flashing bright lights on the big screen, but colors don't make a movie good or bad.

As for the rest, that superman parody says otherwise.

AwesomePromoz - 9/5/2025, 1:10 PM

@OrgasmicPotatoe - You’re a parody of a human being. Youre entitled to your opinion though.

ModHaterSLADE - 9/5/2025, 1:13 PM

I hope we get Creature Commandos in live-action.

LenSpiderman - 9/5/2025, 1:22 PM

Gunn only confused me more. So creature coma does isn’t canon, but potentially everything from the DCEU is? My understanding of peacemaker so far is that it’s made both SS movies canon, which by extension makes the rest of the DCEU canon, but not a comic that is marketed as being directly related to Superman? What exactly is blue beetle in all this? Is clay face in the DCU, or are they actually connecting it to reeves movies as this site has suggested recently? I mean I don’t really care, I guess. As long as we get some decent content, but this statement didn’t clarify anything.
