Despite the hype that next week’s “The Flash” and “Supergirl” musical is getting, executive producer Greg Berlanti admitted that he doesn’t exactly know what the viewers will make of the crossover.

In a recent interview with the New York Times, Berlanti said that he’s not sure about how fans, in general, will react to the musical. But he made it clear that it doesn’t particularly worry him. “Every so often you’re like, ‘if I die tomorrow, if the show went off the air tomorrow, at least we did this episode,’” he told the news outlet.

After all, Berlanti had wanted to do a “Flash” musical episode long before “Supergirl” moved from CBS to the CW. “Greg has been talking about a musical since before ‘Supergirl’ started,” Blake Neely, composer on all the network’s DC comics TV series, told TV Insider. “I think he got it in him when they cast Grant [Gustin for ‘The Flash’]. The man is a creative genius.”

While there some fans who are beyond excited about the musical, there are also some who are less interested in it. For instance, Berlanti’s fellow executive producer Andrew Kreisberg acknowledged that there are some viewers who think that the musical is too much of a stretch — something that he doesn’t personally agree with.

“We have them fighting sentient gorillas the week before, so for us it’s not any crazier or sillier that they’re singing,” Kreisberg explained to the New York Times. In addition, given the oddly high proportion of singers on both cast of the shows, the exec producer said that “at some point it became entertainment malpractice to not do it.”

As previously reported, the first half of the crossover sees Music Meister (Darren Criss) attacking Kara (Melissa Benoist) and putting her in a coma. Clueless about how they can wake her up, Mon-El (Chris Wood) and J’onn (David Harewood) bring the comatose Supergirl from Earth-38 to Earth-2 to ask help from Team Flash. However, Music Meister surprises Barry (Gustin) in the second half of the crossover and puts him under a similar coma. Barry and Kara then wake up without their powers in an alternate reality created by Music Meister where life is like a musical and the only way to escape is by following the script.

The musical crossover event kicks off with Season 2, episode 16 of “Supergirl,” which airs on Monday, March 20. It continues Tuesday night in Season 3, episode 17 of “The Flash,” where the bulk of the action takes place. Both episodes air at 8 p.m. EST on The CW.
