Everyone loves a crossover. Between shared universes like the MCU and DCEU, to TV ones like the Chicago franchise and Netflix's Marvel shows, fans love to see their favorite characters from two different series interact with each other. The CW absolutely killed it this fall with its epic crossover event, and the network has yet another crossover planned for the spring schedule. Because this spring will bring a musical crossover between The Flash and Supergirl. Many fans have been wondering how and why the superheroes will start singing and dancing, although there has been some precedence with the animated series Batman: The Brave and the Bold.
The Brave and the Bold had a musical episode featuring Neil Patrick Harris voicing the original villain Music Meister. It was this villain who uses song to control people, thus creating a reason for lavish musical numbers. Many were hoping he'd be brought to life in live-action with Neil Patrick Harris reprising his role, and now the actor has addressed those rumors with IGN saying,
Well, it appears that Neil Patrick Harris hasn't yet been approached to play the villain in the Supergirl/Flash musical crossover. This might be a major bummer for some, but it doesn't necessarily mean it won't happen in the future.
The upcoming musical crossover has been a big mystery revolving this DC season of television. While both casts have some impressive musical talent, it's unclear exactly how the crossover will work within the confines of the shows. Getting different heroes together in one room is already quite the process, and adding musical numbers might be asking the audience to suspend too much disbelief.
Musical episodes in other TV shows have all needed a specific plot point to explain why the principle cast was suddenly singing their feelings. In Buffy the Vampire Slayer, it was a demon who forced characters to sing all their darkest secrets, and eventually dance until they combust. Both Scrubs and Grey's Anatomy used patients who were suffering from musical hallucinations. Hopefully the folks behind the DC crossover will utilize a smart villain or plot point to explain why Kara and Wally can suddenly sing and dance.
Despite an unclear plot, The Flash/Supergirl musical event has some outstanding talent attached to it. The Flash's Grant Gustin was first known to audiences with his role on Glee, and Jesse L. Martin was in the original broadway cast of RENT. Supergirl's Melissa Benoist was also on Glee, Chyler Leigh sang a song in the musical episode of Grey's Anatomy, and Jeremy Jordan is a Tony nominated Broadway actor.
