Tuesday, March 21 will bring us “Duet,” the fuller part of a 2-part crossover in which characters from Supergirl go to The Flash for a musical episode.
Melissa Benoist (Kara), Chris Wood (Mon-El), and David Harewood (Hank Henshaw) will all be making the leap to that other CW show, which is just as good as getting two Supergirl episodes in one week, right? (Supergirl “Star-Crossed” airs the night before.)
Here’s how The CW describes the Flash episode; some official photos follow below. Award-winning songwriters from La La Land in addition to Crazy Ex-Girlfriend’s Rachel Bloom will be contributing music to this event.
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. Dermott Downs directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Aaron Helbing & Todd Helbing (#317). Original airdate 3/21/2017.
