Greg Berlanti on the Flash/Supergirl musical, four-show crossover

Arrow, The Flash, DC’s Legends of Tomorrow and Supergirl executive producer Greg Berlanti has talked to IndieWire about the four shows’ upcoming, anticipated seasons and how they will crossover. Berlanti previously announced that a The Flash/Supergirl musical crossover would be happening and air as two episodes of the respective shows.

“We just finished writing the fall crossovers,” he told the site. “And now we’re trying to figure out how to produce them. That’s probably the most challenging thing we do all year. And now we’re doing it across three shows! But 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.”

He added that he couldn’t say who they are talking to yet, but he “did speak to someone we’re really excited about. There are some writers I’m incredibly excited to work with.”

Regarding the crossover that will happen with all the shows, Berlanti had this update:

“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.”

All four of the shows are set to premiere this October, beginning with The Flash on Tuesday, October 4, then Arrow on Wednesday, October 5, Supergirl on Monday, October 10, and DC’s Legends of Tomorrow on Thursday, October 13.
