Could a Flash/Arrow/Supergirl television crossover be close to materializing?

Despite CBS chairman, Nina Tassler previously downplaying any potential for a crossover between Supergirl and the shared DC Television Universe hosted by The CW, it now seems like the network could be warming up to the idea. When speaking about Supergirl at the Television Critics Association Winter Tour today, CBS president, Glenn Geller said something that has united a flurry of speculation amongst DC Comics fans.

Flash, Supergirl - ArtThe speculation began from a seemingly innocent question that spawned from Supergirl star, Melissa Benoist and The Flash star, Grant Gustin presenting together at the Golden Globes this past Sunday. When asked about the possibility that Benoist’s Supergirl could one day meet Gustin’s Flash on the small screen, despite the shows not airing on the same network (though CBS Corporation co-owns The CW with Warner Bros.), Geller stated, “I have to be very careful what I say here. Watch and wait and see what happens” he told reporters at the scene, which was later corroborated by official source, TheWrap.

While this isn’t an outright confirmation that Supergirl and The Flash will cross over in the near future, it does seem to indicate that CBS is possibly warming up to the idea of letting the Girl with Steel’s series retroactively enter the canon of The CW’s DC Television Universe, and may already be negotiating it. Supergirl and The Flash (and Arrow, for that matter), are already being cross-promoted, having press releases and publicity photos released at the same time, even with Supergirl technically on a separate network, and since Supergirl was originally pitched to The CW, who passed on it at the time (and later regretted it, as recently confirmed by their president), it’s especially worthy of speculation that the Girl of Steel may eventually team up with The Flash, or Green Arrow, on the small screen, if not the soon-debuting Legends of Tomorrow. It’s also worth noting that The Flash, Arrow and Supergirl share executive producers in Greg Berlanti and Sarah Schechter.

Even if CBS wanted to keep Supergirl in its own private universe, this could potentially accommodate a crossover with The Flash, as its title hero recently gained the capability to hop between parallel worlds in the show’s currently-airing second season. It’s possible that the Supergirl universe could be treated as another parallel universe for Barry Allen to eventually stumble into, though this would likely eliminate crossover potential with Arrow, unless Melissa Benoist’s Supergirl also flew back to the opposite side for some reason or another.

We’ll be sure to keep an eye on the crossover possibility between Supergirl and the DC Television Universe, but for now, keep flying to Eggplante for all news and updates on DC’s television projects.
