CBS President Says Supergirl Crossover WIth Flash/Arrow Unlikely

Nobody will rule out the possibility that CBS' upcoming Supergirl series, produced by Arrow and The Flash showrunner Greg Berlanti, will cross over with those two series, which air on the CBS co-owned CW Network.

There are even reports that Berlanti has it built into the language of his contract that such an event is allowed.

The president of CBS, though, is somewhat less bullish on the prospect -- at least right away -- and said as much as the TCAs, according to IGN.

"Well, those two shows are on a different network," Presdent of CBS Nina Tassler said. "So I think we'll keep Supergirl to ourselves for a while."

Of course, Warner Bros. Television, Berlanti's production company and DC Entertainment will also have feedback into the process, but it's unlikely they'll want a fight over something like that with Tassier and CBS right away...and if the shows all continue to do well, the odds seem better that she'd be open to sharing the screen once Supergirl is established.

In the meantime, though, the word "independent" came up -- which is somewhat hard to be when everyone is wondering what crossover is just around the corner.

"It's a wonderful amalgamation of the mythology of the character with a coming of age tale," said Tassier, who also helped develop Lois & Clark: The New Adventures of Superman for ABC. "She's a very strong, independent young woman and she's coming into her own. She's dealing with family issues. She's dealing with work issues. And it's a female-empowerment story, which if you look at the strong female characters we have on the air, it really is resonate to that."
