And now we’ve got our first hit of unadulterated joy in the form of the first pictures from the special episode.AdvertisementEntertainment Weekly has a new gallery of images from “Duet,” the Flash side of the two-parter, which will see Batman: The Brave and the Bold villain Music Meister (played by Darren Criss) trap Kara and Barry in an alternate reality—one where they’re stars in a musical movie, and their best friends are the supporting cast. The only way to get out is to follow the Music Meister’s orders, and see the script of his “movie” through to its end.And also, it seems, dance a lot. This is adorable.AdvertisementAs well as Kara and Barry in action, the images give us our first look the rest of the cast in the alternate reality world, as well as Criss in costume as Music Meister—with Winn on the piano. Sadly, he’s not wearing his amazingly garish outfit from Batman: Brave and the Bold though.Head on over to EW to squeal in delight at the rest of the images at the link below. The crossover will kick off in the climax of Supergirl’s March 20 episode, before continuing the day after on The Flash.[EW]He's the Music Meister, and We Must Beware His WrathEveryone You Want to Sing in the Flash/Supergirl Musical Crossover Will SingAs Demanded by Common Sense, Supergirl and Flash Are Going to Have a Musical CrossoverThe Supergirl/Flash Musical Episode Has Found Its Music MeisterJames Whitbrookjames.email@example.com@JWhitbrookJames is a staff writer for io9.
