Following a brief tease, The CW has now released the full trailer for the upcoming “The Flash” and “Supergirl” musical episode crossover event.
Set to air next week, the “Flash” episode sees Mon-El (Chris Wood) and Hank Henshaw (David Harewood) arrive on their Earth carrying a comatose Supergirl (Melissa Benoist) who was whammied by the Music Meister (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 to the end.
Benoist, Grant Gustin, Jesse L. Martin, Victor Garber, John Barrowman, Jeremy Jordan and Carlos Valdes reportedly all have singing parts in the episode..
