Despite being on different networks, the possibilities of a crossover between CW's The Flash and Supergirl are possible because they are both DC Comics properties.
They seem even more likely now following comments made by CBS president, Glenn Geller when asked if the two super heroes could crossover much like Arrow and Flash do annually.
“I have to be really careful what I say here,” Geller said on the Television Critics Association press tour. "Watch and wait and see what happens,” he concluded.
The answer is quite different in comparison to that of former CBS president, Nina Tassler, who bluntly stated, "Right now we're not doing it."
Supergirl and The Flash share a few executive proders in Greg Berlanti, Sarah Schechter, Andrew Kreisberg and Geoff Johns.
