‘The Flash’ and ‘Supergirl’ cross over musical event is just weeks away!

Good news for the fans, we get new and exciting details about the singing characters we love so much! Flash and Supergirl take on a musical villain, which means musical action!

A recent interview from Entertainment weekly gave us, “In a nod to Kara’s favorite film, Wizard of Oz. Everyone else in the vocally impressive cast is playing a character within this movie, from Jesse L. Martin, Victor Garber, and John Barrowman as rival mob bosses to Jeremy Jordan’s club pianist and Carlos Valdes’ aspiring artist busboy.”

The amount of musical talent in this episode is going to be bananas. Almost everyone involved has some sort of history in the musical world, including Rent star Jesse L. Martin, who plays Detective West. Most surprisingly, Grant Gustin, Flash himself even sings!

According to my source, inspiration pulled from Guys and Dolls, Singing in the Rain, and West Side Story.

We have to wait until March 21st for this epic musical, but until then we get all the insider details.

DARREN CRISS (“GLEE”) GUEST STARS AS THE MUSIC MEISTER IN THE FLASH AND SUPERGIRL MUSICAL CROSSOVER – Barry (Grant Gustin) and team are surprised when Mon-El (guest star Chris Wood) and Hank Henshaw (guest star David Harewood) arrive on their Earth carrying a comatose Supergirl (guest star Melissa Benoist) who was whammied by the Music Meister (guest star Darren Criss). Unable to wake her up, they turn to Team Flash to save her.

However, the Music Meister surprises The Flash and puts him in a similar coma, one that Team Flash can’t cure. Kara and Barry wake up without their powers in an alternate reality where life is like a musical and the only way to escape is by following the script, complete with singing and dancing, to the end.

The Flash airs Tuesday Nights at 8/7c on The CW.
