Flash Supergirl Musical Poster Debuts

The Flash Supergirl musical crossover debuts on The CW next week

The CW has just revealed a special poster design for next week’s The Flash Supergirl musical crossover. Check it out in full in the gallery viewer below!

The Flash Supergirl musical begins with Supergirl episode 2.16 on March 20. Titled “Star-Crossed,” it is officially described as follows:

“A new villain (guest star Teri Hatcher) comes to National City, putting Supergirl (Melissa Benoist) on high alert. Meanwhile, Winn’s (Jeremy Jordan) girlfriend, Lyra (guest star Tamzin Merchant), gets Winn in trouble with the law. Maggie (guest star Floriana Lima) attempts to help Winn but old loyalties get in the way. The Music Meister (Darren Criss) attacks Supergirl.”

The Supergirl Flash musical then continues with The Flash episode 3.17, “Duet.” This is where the singing starts. It is set to air on March 21 and is described as follows:

“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.”

Dermott Downs directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Aaron Helbing & Todd Helbing.

Title heroes Grant Gustin and Melissa Benoist are confirmed to have singing parts in the episode along with Jesse L. Martin, Victor Garber, John Barrowman, Jeremy Jordan and Carlos Valdes.
