Since the beginning of the DC Comics TV shows, the question on every fans mind was, “How big will this get?” First came Arrow, then Flash and Gotham, and now Legends of Tomorrow and Supergirl. Yet, as executive producer Andrew Kriesberg pointed out to Entertainment Weekly, just because they were created, didn’t mean they were all connected:
“If Supergirl and Flash were existing in the same universe, then why has no one on Flash or Arrow ever talked about Metropolis or the fact that there’s a Superman?” Kreisberg points out. “The one explanation for that is because he doesn’t exist in that world.”
So then the question became, “Will they crossover eventually?” Well, in a week, Flash and Supergirl will crossover. Which made Grant Gustin (the Flash) very happy, and he notes to EW that he wants all the DC shows to crossover if possible. Kriesberg adds to this when discussing the race between Supergirl and flash that’ll happen in the show:
“It’s one of my favorite moments in this episode,” says Kreisberg. “It’s close.” Hopefully close enough that they’ll need a rematch next season, maybe with Green Arrow and the Legends as an audience. “That’s in the cards at this point,” says Gustin. “The whole point of us doing this crossover is setting up the fact that maybe next year we can cross over all of them.”
We’ll see just who goes where later on, but next Monday we’ll see Supergirl and Flash race to see who’s the fastest on CBS.
