From virtually the moment it was announced that Arrow and The Flash executive producer Greg Berlanti was developing another DC project in Supergirl, there’s been speculation about a potential crossover between the shows.
However, given that Supergirl will air on a different network to her fellow DC superheroes, it would seem the chances are slim, and indeed CBS chairman Nina Tassler confirmed as much back in January. Still, Berlanti himself hasn’t quite given up hope, telling Variety that:
“The network has said publicly at this point they’re going to keep her to themselves. I always approach the shows as a fan first, so I would love to see [a crossover]. I think in success, all things are possible. But there’s a lot that would have to happen before everybody might say yes to that.”
