Supergirl Could Possibly Exist In The Same World As Arrow & Flash
The December 5, 2014 issue of Entertainment Weekly magazine - now hitting newsstands - features a profile on Greg Berlanti, the executive producer of many current hit shows including Arrow, Flash, and The Mysteries of Laura. It's a fascinating article about his approach to the different series, talking about his origins in the business with shows like Dawson's Creek and his one comic-based project that wasn't so much of a hit, the Green Lantern movie.
As has been mentioned before, one of Berlanti's new projects is a Supergirl TV project for CBS, which he is developing with Ali Adler and Sarah Schechter. There's a section talking about what's currently going on in production, and there's a very interesting nugget within:
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.
