The photo comes as part of a cover story on executive producer Greg Berlanti, who counts the CW's Arrow and The Flash and CBS' Supergirl among his series, along with the upcoming DC-based Legends of Tomorrow for CW. When it came to the question of whether CBS will let Supergirl do crossovers with the DC Comics series on CW -- something Berlanti has previously expressed interest in -- he told Variety that while he'd love to see Supergirl join forces with those DC superheroes, it's not currently in the cards. "The network has said publicly at this point they’re going to keep her to themselves,” he said. “I always approach the shows as a fan first, so I would love to see [a crossover].Is there any possibility though that things could change? Says Berlanti, "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.” CBS president Nina Tassler has struck down the Supergirl crossover ideas with Arrow and The Flash in the past, citing the TV series airing on different networks. However, CBS co-owns The CW and Berlanti is behind all the shows, so there is wiggling room for the crossover to possibly happen.Supergirl is set to air later this year on CBS on Monday nights
