CBS’s Supergirl has ended up being extremely popular, and DC fans are still wondering if it could cross over to the Arrowverse as they’re produced by the same people.
â€œI would love it, a lot of things would have to go right and people would have to say â€˜Yes,â€™â€ Berlanti said. â€œIt 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 weâ€™ve talked internally about how cool it would be, but we havenâ€™t had official conversations. [The CW chief Mark Pedowitz] is supportive.â€
Since it seems like there is a deadline, it almost sounds like they’re hoping for this to happen in this season and not sometime in the future. If Supergirl were to crossover to the Arrowverse, that would add some potentially awesome characters to the larger DC TV universe including Martian Manhunter!
