Now at the Television Critics Association press tour, it's learned the two shows will have a musical crossover.
“Yes, there will be a musical crossover,” executive producer Greg Berlanti confirmed. “There’s going to be a musical pair of episodes in the back half of the year between Supergirl and Flash.”
Regarding the music the pair will be singing, Berlanti offered,"I think they’re going to be mostly preexisting songs.”
EW.com also notes a lot of The Flash and Supergirl cast have musical talents, which also includes Jesse L. Martin and Jeremy Jordan.
“Some of you may know my own personal love of musicals and actors who have been in them, and we have a number of people who can sing across all the shows who will be making some very exciting appearances in the back half of the year,” Berlanti said. “I’ve probably been leading the charge myself just because my own nexus of loving musicals and loving superheroes,” Berlanti said. “So many times it’s a musical episode off the set, and I think on all the shows, we love to use all of the character talents as much as possible. We’ve toyed with who potentially the villain could kind of be. My sense is we’ll be very careful about how it is they kind of break into song and there will probably be an element of being in some character’s head at the time.”
