As the small-screen version of the DC Universe has grown, its producers have embraced that most comic-book of concepts: the crossover. We've seen Arrow on The Flash, The Flash on Arrow, Arrow on Legends of Tomorrow, Constantine on Arrow, and the list keeps going. Because the Warner Bros.-produced Supergirl is on a different network, though, you had to wonder if producers could make crossovers with that show work (sure, we got Constantine on The CW, but his show was already over). Well, now we know.

Greg Berlanti (pictured above with his heroes) and Andrew Kreisberg, who served as executive producers on both shows, announced today that we'll see The Flash cross over with Supergirl this spring, as Barry Allen heads to National City. We don't know any plot details other than that, but this is very exciting news for an ambitious group of writers and producers who've developed an enthusiastic fanbase for these interlinked shows. 

"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," Berlanti and Kreisberg said. "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.”

There were no doubt some interesting logistical hoops to jump through to make this even worth it, and now we're left with some interesting questions. The Flash has already established the concept of multiple Earths, so which one does Kara live on, and if she's on the same one that Barry Allen's on, does that mean Oliver Queen can ultimate drop by too, or Felicity Smoak? Could Kara ultimately show up to time hope with the Legends of Tommorrow for a while? All interesting, and exciting, possibilities.

The Flash/Supergirl crossover will air March 28 on CBS. We're hoping for an awesome race.
