When it was first announced that Greg Berlanti and Ali Adler were developing a television series around Supergirl, many (including myself) immediately wondered if it were possible for the last daughter of Krypton to share the same canonical universe as any of the other current DC Comics shows, such as The Flash and Arrow, which Berlanti also produces. Those hopes were diminished, however, when the series got picked up by CBS, and not by The CW, the current home of the aforementioned Scarlet Speedster and Emerald Archer.
Despite that, Berlanti has added more fuel to the flames of geeky speculation by teasing the possibility that such a crossover could still happen. The latest edition of Entertainment Weekly turns the spotlight on Berlanti and his various projects, and the piece included this little update about Supergirl‘s development:
Later in the afternoon at his other office on the Warner Bros. lot, Berlanti meets with fellow producer Ali Adler and Oscar-winning costume designer Colleen Atwood to go over looks for their upcoming revamp of Supergirl. The show will follow 24-year-old Kara Zor-El, Superman’s cousin, and with a twist that that could melt fanboy brains, Berlanti says it’s possible this Supergirl could enter the worlds of Arrow and The Flash.
