Supergirl and The Flash fans may still be on the lookout for more details of the upcoming musical crossover featuring the Music Meister. But the team behind the series is already gearing up for the bigger crossover in the DC TV universe.
Speaking to TV Line, Executive Producer Andrew Kreisberg revealed that the networks are already matching up schedules to ensure that the crossover will happen smoothly.
"We're hoping to do a true four-way crossover. The great thing about our dear friends at The CW and [network president] Mark Pedowitz picking the shows up as early as they did [is that] it has allowed us to start building the schedules for the next season. One of the big things we learned from two years ago, which made the crossovers slightly easier this year, was built-in shutdown days, where shows just went dark because the single hardest factor in doing the crossovers is actors' availability while the four series simultaneously continue production."
As for Supergirl's part, Kreisberg revealed that it's the series that will be experiencing this shutdown the most, given its recent transfer from CBS to The CW.
So, what should fans hope for with the crossovers of these superhero series? At the very least, not the appearance of doppelgangers in the crossovers. And unless there can be one great overarching story that involves them, Kreisberg says they will be avoiding these storylines so they won't have to deal with the opening of "the floodgates of insanity."
For now, fans can look forward to the Supergirl/The Flash crossover, which will be sounded off by the final episode of Supergirl on March 20.
