Berlanti Talks DC CW Four Series Crossover

In a few months we’ll see The CW’s four DC Comics inspired shows – “Arrow,” “The Flash,” “Legends of Tomorrow” and “Supergirl” – coming together in a four-episode, four show crossover. Greg Berlanti, who serves as an executive producer on all four, tells Indiewire they’ve just finished writing the Fall crossovers and are now trying to figure out how to produce them.

“You really are trying to run a single production across three different productions. But they’re run as three separate entities. We have to figure out when we’re borrowing one actor from where. We’re telling one cohesive story; ‘Supergirl’ will participate, but the storyline doesn’t actively begin there. There are some characters who show up in her episode, but the story begins with ‘The Flash’ episode and goes to ‘Arrow’ and ‘Legends of Tomorrow.’

We’re just getting into designing the bad guy for it, and we start now but it doesn’t air until the end of November. We will put a lot of time between now and then figuring out visual effects sequences. Just today I was holding the three scripts back-to-back – that’s 180 pages of material. It’s a three-hour story, almost a miniseries.”

He also spoke about the two upcoming musical crossover episodes between “The Flash” and “Supergirl,” with music for those episodes now going through a clearing stage:

“Next week we’ll have to start talking about clearing music. I have a few ideas for tone and style in my head but we’re just starting to talk about what that can be. I do want to try and get an original piece of music written. As we make a deal on that we’ll probably make some announcements on the original songs. [We] did speak to someone we’re really excited about. There are some writers I’m incredibly excited to work with.”

Jonathan Schaech is also set to return as Jonah Hex for the second season of “Legends of Tomorrow”. All four shows return in the first two weeks of October.
