Ever since CBS's Supergirl was announced, there's been a constant question as to whether the show would crossover with CW's Arrow or Flash. Greg Berlanti, executive producer of all three shows, has been cagey about the prospect at best. But now, it seems like the chances are better than ever, specifically with Flash.
“I would love it, a lot of things would have to go right and people would have to say ‘Yes,’” Berlanti told Entertainment Weekly. “It would have to figured out very soon. It would all have to be figured out in the next month or so. As it remains right now we’ve talked internally about how cool it would be, but we haven’t had official conversations.”
Berlanti also added, “[The CW chief Mark Pedowitz] is supportive," meaning that at least one network is on-board.
Supergirl airs Monday nights on CBS, while Flash airs Tuesday nights on the CW.
