Yes, yes, I know what you're thinking- but DC confirmed the universes are seperate. And yet, as I've been telling people from the moment of this announcement, that doesn't rule out a crossover. Why? Because if there's one thing DC is known for, it's not just it's universe of expansive characters and stories, it's the fact there are multiple ones of those. And every now and then they collide.
So when DC first said that Arrow, Flash, Constantine and Gotham, plus likely new additions Titans, Hourman and Supergirl- and let's not forget the talked about Suicide Squad- weren't connected to the DCCU, and people complained, I told people to think of it as a multiverse. After all, even if it didn't happen, there was no way to prove they didn't exist alongside each other in different universes. As it happens, Geoff Johns is of a similar persuasion: and he made it pretty clear a crossover is possible.
Sure, he didn't confirm one, but he said that it's certainly possible, and in future, if the opportunity arises, they'd sure do it. But they wouldn't do one just for the sake of it. To be honest, I support this idea: I like the shows being separate. I worship them, but they're not shackled to the film universe, and instead are allowed the freedom of a whole DC Universe of their own, while plausibly still being able to meet the likes of Henry Cavill's Superman down the track.
Johns told Buzzfeed:
We look at it as the multiverse. We have our TV universe and our film universe, but they all co-exist. For us, creatively, it’s about allowing everyone to make the best possible product, to tell the best story, to do the best world. Everyone has a vision and you really want to let the visions shine through. I think the characters are iconic enough. I like [Marvel’s Agents of] S.H.I.E.L.D. a lot. I love what Marvel does. I’m a huge fan. It’s just a different approach.
As a fan of both DC and Marvel, I share his convictions. While Agents of SHIELD has certainly worked into a show of its own right, no one can deny that while being connected to the MCCU is great, in the first season it's inability to do anything the films wouldn't allow worked against it rather than for it, shackling it to certain decisions and inabilities to use certain locations or characters. At its worst it felt like a glorified cameo fest, which has thankfully improved.
Johns went on to say,
There’s been discussions over the years for both, obviously. You never say never. Maybe one day we’ll link a show to a film if it makes sense, but the creative process we’re going through right now is to let the stuff live and breathe and be its own thing and own it.
And I applaud DC for this movie. It's thought out, sensible, and doesn't make anything impossible, as well as being consistent with the nature of the comics.
With the above direct reference to Crisis on Infinite Earths, a multiverse crossover story, it's entirely possible we'll see it very soon, and I hope we do, as well as allowing the universes to thrive and be their own thing.
