Supergirl-Flash Crossover: EP Andrew Kreisberg On How It Came Together & What Else The Multiverse Might Hold
SPOILER ALERT: This story from Deadline.com contains details of tonight’s Supergirl and The Flash crossover episode on CBS.
“I think that one of the best parts about the show is it already seemed like Grant has been on Supergirl for a long time,” executive producer Andrew Kreisberg says of Flash star Grant Gustin’s crossover appearance tonight on the CBS superheroine series. Now, crossovers are nothing new to the small-screen versions of the DC Universe, but Monday they jumped worlds and networks with freshman Supergirl and star Melissa Benoist welcoming The CW’s The Flash, which is in its second season.
