Warner Bros. and DC have announced 13 movies, not including its Vertigo slate, for the immediate future. They also have four different TV shows on the air, with more to come. The big question fans have is: How do these projects all tie together? Well, as DC creative chief Geoff Johns explains it, all of these DC movies and TV shows form a multiverse.

Basically, The CW's The Flash and Grant Gustin's Barry Allen exist on a different plain of reality from Ezra Miller's version of the character in 2018's big screen standalone adventure The Flash. And the same stands true for NBC's Constantine and Fox's Gotham when it comes to The CW's Arrow and CBS' Supergirl. If characters are to crossover between networks with the big screen characters of Justice League, it sounds like someone is going to have to enter a wormhole.

While these spinoff and franchises will all remain separate for the time being, they do co-exist in this crazy multiverse. Geoff Johns explains:

Arrow and Flash are the same universe, and we get a lot of great story out of that - especially when we have episodes that cross them over, but that's also where our superhero universe lives. 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."

He further explained DC's approach to sharing various characters between the movie and TV universes:

We don't want to be policemen. The last thing in the world that we want to do is say no to something. The best thing we can do is work with the producers and try to be additive and collaborative and try to figure out how to expand it. Firestorm's role in The Flash grew organically, but now it's become something big and great because we can get Firestorm out there and his Rogues and everything. The key for all of this is to expose more of the DC universe and the Vertigo books to people so they fall in love with them too. We share that love of these characters. So for us we'd rather expand than contract."

One thing we shouldn't expect anytime soon is a crossover between the DC cinematic universe and the TV universe, though its not beyond discussion.

"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."

What do you think of Geoff Johns idea of a Multiverse? Were you hoping DC would take more of a Marvel approach?
