James Gunn is rewriting history to suit his own purposes. But it’s okay because it’s not the Smithsonian and he’s not the President of the United States. Gunn’s actually just retconned a show everybody liked from a cinematic universe many did not to fit into a new one. No big whoop, really, but it is very smart. When Gunn made his mark in DC movies and shows with The Suicide Squad and its follow-up, Peacemaker, the DCEU was a shell of its former self. So why not eschew the bits that tied it to the old and tie it into the new?
This, of course, led to one of the cleverest retcons in TV history. In the “last season on” recap before Peacemaker season two, episode one, we saw the titular hero coming across new DCU heroes (Mister Terrific, Superman, Green Lantern, Hawkgirl, and Supergirl) instead of the old DCEU Justice League. Wicked Smaaht, as the Bostonians would say.
Gunn recently addressed those changes in an interview with Rotten Tomatoes. He said:
“Peacemaker was always in a weird place. People say he was part of the DCEU but he wasn’t really. He was part of this “in-between Universe” of DC when there was nobody really making sure that everything was connected and at a time when they were going to rewrite everything with The Flash.
We were kind of able to do whatever we wanted and we had that brash ending, which I loved, it was one of my favorite things from the whole season, but it just didn’t fit in with the DCU. And Peacemaker, there’s hardly anything else that you need to change for him, he can slide very easily into the DCU, same with Blue Beetle. They just kind of fit in very nicely, we just have to retcon a couple of things.”

I’ve said it before, but why wouldn’t Gunn want to take some of the best work of his career with him into the new cinematic universe he’s in charge of? Sure, it’s picking and choosing, but that’s comic books for ya. He’s keeping Blue Beetle, too, so it’s not like it’s only his own shiz.
Later in that same interview, Gunn shared that Peacemaker season two is as integral to the early chapter of the DCU as Superman and Supergirl.

We’ll of course see where all of this goes, but the DCU is off to a pretty killer start. Even if, as Gunn said, not all of the upcoming projects directly tie in to the overall story arc, it’s already shaping up quite nicely.
