Berlanti promises that each of the three shows will be distinctive.
"The team-up show honors the spirit of things like those Westerns like 'The Magnificent Seven' or those team-ups in the books, when it really, it takes a village," he says.
As we've established, Berlanti notes, "There's a couple characters being plucked form each and then some new characters being brought in," but he adds that the producers have a sense of how to keep the original shows from losing their distinctiveness.
