During The CW’s recent Television Critics Association press day Executive Producer Andrew Kreisberg spoke at length about the upcoming musical crossover between “The Flash” and “Supergirl”.
“Hearing Melissa [Benoist] and Grant [Gustin] sing – it’s funny!”, he said. “You guys only ever see the episode. To me it’s like, I think about every episode, it’s also the experience of making it. I can’t tell you how many times I’ve been on set with Melissa, or when Melissa and Grant were there. They were just singing between takes. So it’s like, I hear Melissa sing all the time. So for you guys to get to hear that finally will be so great.”
“What I love about it, and it’s what I always loved about what Joss Whedon would do like with Hush, or The Body, he’d have these very special episodes, but they were intrinsic to the storytelling, the ongoing storytelling that was going on. So when we get to the musical episode, both Barry and Kara will find themselves at pivotal crossroads on their respective series, and the experience of going through the musical will have a great impact on both series moving forward.”
“There are going to be people from both shows singing. It’s going to start on Supergirl, and it’s going to resolve on Flash.”
“We’ve had singing on Flash before. We had Barry sing karaoke. We had Jesse sing in the alternate universe. But to be able to have a full-fledged musical episode, as much as we hope these shows speak to people, whether socially, or Alex’s storyline and what it means to people, at the end of the day, we’re trying to entertain people. We feel like no one is trying harder to just flat-out entertain people than this quartet of shows. So to be able to do a musical episode is so exciting.”
The villain of the as-yet untitled musical crossover will be Music Meister, a DC Comics character who uses his singing voice to create a pitch so high that it hypnotizes people. In their state of hypnosis his victims are forced to sing and dance.
