CW Already Planning Next Season’s DC Crossover

“Arrow” executive producer Andrew Kreisberg has teased that The CW’s DC series are already planning out next season’s crossover episodes.

In a new interview with EW, Kreisberg explained why the “Supergirl” episode was barely connected to this year’s ‘Invasion’ crossover and how that will be rectified with next year’s team-up episode for a true four-way mashup:

“Because we weren’t aware that we were going to switch ‘Supergirl’ from CBS to CW and it was really going to be part of it — that was the one show that didn’t have built-in shut-down days, so all the other ones did.

Melissa [Benoist] ended up being heavily in Flash and then in Arrow, so Supergirl was the one we needed to shut down the most and it was the one that we didn’t have any opportunity to.

Now that we’ve gotten the early pickup and we’ve started designing the seasons, we’re building in those dark days, and actually more dark days on Supergirl than the other shows, to make it a little easier… Next year, we’re hoping to do a true four-way crossover.”

“The Flash” and “Supergirl” will deliver an anticipated musical crossover episode next month featuring Darren Criss as the Music Meister.
