The CW President Mark Pedowitz declined to confirm whether the CBS Supergirl would crossover with Arrow and Flash; instead, telling reporters at the Winter TCA's to ask executive producer Greg Berlanti. Well, that's exactly what IGN did. Berlanti told the gaming site, "So much has to go right for us to be able to make a great show. Again, I think of myself as like if I were watching them, I would want to see [them crossover]. But we have to get so many things right to make a good show and so much of it is luck, unfortunately."
As far as actual progress on the Supergirl show is concerned, Berlanti shared, "I hope you’re going to hear about casting soon or we’re not going to be able to make the pilot! I would say, tonally closer to Flash than Arrow. That’s probably the best way to say it."
It sounds as if Berlanti definitely wants to make the crossover happen. And as previously reported, the ability for Supergirl, Flash and Arrow to crossover is something specifically outlined in Berlanti's contract. For now, it appears that Berlanti simply wants to get the titular role cast and the pilot filmed before confirming any crossovers with The CW's superhero duo.
