The DC TV universe is growing. With the success of CW's Arrow and the promising first episodes of Flash, its no surprise that Supergirl found a home quickly. Some had hoped that the CW would have picked Supergirl so the Arrow-verse could grow by another show. Well despite Supergirl being on the CW, it sounds like cross-overs might be possible.
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.
