The Flash and Supergirl crossover is happening, and here’s how it will probably go down
Since the moment CBS announced that it was developing a Supergirl TV show produced by Arrow and The Flash’s Greg Berlanti and Andrew Kreisberg, fans have wondered if there will be an internetwork crossover between the shows.
Despite a crazy amount of red tape, that crossover is now confirmed.
Berlanti and Kreisberg issued the following statement:
We are so incredibly excited to announce something that we have dreamed of happening since we starting making SUPERGIRL – THE FLASH and SUPERGIRL are teaming up! We want to thank Grant Gustin for making the time to come visit (on top of his already immense workload) and all of the folks at CBS, The CW, Warner Bros. and DC for working this out. And finally, thanks to the fans and journalists who have kept asking for this to happen. It is our pleasure and hope to create an episode worthy of everyone’s enthusiasm and support.
On the one hand, CBS does have a stake in the CW. The shows share producers, so creatively, it was an easy fit. Still, for as many connections as there are between the networks, they are two separate entities, making any crossover massively complicated to arrange.
There’s also the cynical question of who benefits the most (beyond the fans). There are probably a few execs that aren’t thrilled to be promoting another network’s show, so the financials were probably a sticking point.
Yet somehow, despite all the obstacles, the networks apparently got it together. The crossover will take place on March 28, on CBS’ Supergirl.
Details on the episode haven’t been released yet, so it isn’t clear exactly how they will explain the crossover. There is a very obvious answer though.
This season The Flash introduced the concept of the multiverse, a long-standing DC Comics staple. Originally the idea was used to introduce two Earths, one featuring the golden age characters and the Justice Society, while the other contained the silver age heroes and the Justice League. That concept eventually expanded, giving writers the freedom to introduce alternative storylines without contradicting existing canon. The multiverse grew.
The Flash is currently exploring its Earth 1 (the Arrow/Flash Universe), and Earth 2 (containing alternative versions of the characters including the golden age Jay Garrick as The Flash) was recently introduced. Supergirl is set in its own universe, and it could easily be just another Earth. The Flash has the ability to travel between realities, so he could find himself on Earth 3 (or whatever the Supergirl Earth is called).
That would be an easy and clean way to do the crossover. The characters could interact without any real consequences for the larger stories each show is telling. More than that though, it could theoretically connect every DC movie and TV show ever made. They could all just appear in their own, separate universe.
If this is the route they go – and it would be shocking if they don’t – that could make it tough to set up a future Arrow/Supergirl crossover. The character of the Arrow (now Green Arrow) doesn’t have the capabilities to reach multiple Earths. Besides, their powers/skills wouldn’t really compliment each other.
Supergirl could always appear on the CW shows, but it’s probably easier for the CW to come to CBS than the other way around.
Of course, The Flash appearing on Supergirl could always be another Flash – an alternate Barry Allen from a previously unseen Earth not directly connected to the show – but that would be a frustrating way to present the crossover.
Expect to hear more on this in the coming weeks.
