As rumored in recent weeks, CBS’ “Supergirl” will indeed move to the more compatible (and more cost effective) The CW for season two in 2016-17. “Supergirl” will join “Arrow,” “The Flash” and “D.C.’s Legends of Tomorrow” in the expanding DC superhero universe on The CW. And one of them, “The Flash,” already featured a crossover episode with “Supergirl” this season.
In addition, production of “Supergirl” will shift from Los Angeles to Vancouver, Canada where the aforementioned CW dramas all film. The number of episodes ordered has not been confirmed.
