Supergirl/Arrow Crossover: 'A Lot Would Have to Go Right for That to Happen'

What is the latest outlook for Supergirl to take flight to The CW for a crossover with Arrow or The Flash?

“Unfortunately, you’re going to get the same answer that I always give, which is that, as a fan, I would love it,” Greg Berlanti, the prolific producer behind both the CBS and The CW’s superhero series, said Sunday at the Television Critics Association winter press tour in Pasadena.

“I personally never rule anything out,” he continued. “I would be excited by it. But a lot of things would have to go right, people would have to say yes, for that to happen.” What’s more, to stand any chance of happening this TV season, “It would have to be figured out in the next month or so.”

In addition to “financial hurdles” and the corporate challenge of “getting everybody to sign off,” any potential crossover would also need to address one super-sized creative issue.

“You haven’t been hearing about Superman [on Arrow/The Flash], and Superman exists in [Supergirl’s] world, so we’d have to figure out a way around that,” Berlanti explained, adding that the creative team has “some thoughts” on solving that problem.

However, the EP noted that while the producers “have talked internally about how cool we think [a crossover] would be, we haven’t had any official conversations with anybody.” (With reporting by Matt Webb Mitovich)
