Have to say i’m somewhat surprised this is happening so soon, but CBS has just announced that The Flash will be paying a visit to National City to meet Supergirl in March this year! What made this a rather more unlikely prospect than the Flash/Arrow crossovers we’ve seen is that, unlike in the UK where all the shows are on Sky 1, in the US, The Flash airs on The CW, and Supergirl is on CBS. Although they are 2 separate networks, they do have the same parent company, and both shows are made by Berlanti Productions. However, the bosses at CBS had initially ruled out any sort of crossover, as they wanted Supergirl to stand as a separate entity.
Greg Berlanti and Andrew Kreisberg said “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.”
Whilst Arrow isn’t joining Barry and Kara in this one, the important thing is it establishes that they do all share the same universe. This not only means there’s potential for Green Arrow to pop up in the future, it would also mean more characters could be passed back and forth. That would mean a certain green skinned Martian could pop up on Flash or Arrow, or even Supergirl herself. It also establishes that Superman exists in the Flash/Arrow universe, which is something that’s not been totally clear up until now. Still no word on Batman or any of the extended Bat-family, but I have my fingers crossed!
The Supergirl crossover episode airs in the US on the 28th March on CBS, but it’s hard to say exactly when that means it’ll air over here. Sky had got Supergirl returning 1st April, one month after Flash/Arrow and Legends of Tomorrow which air on the 1st, 2nd & 3rd of March, but at the moment we don’t know if that’s due to CBS having more gaps in their schedule than The CW, or if they were just planning on running it later as their wasn’t any crossover. We’ve asked Sky for comment, so we’ll let you know what they say.
