See A First Look At Darren Criss In The Flash/Supergirl Musical Crossover

Shortly after revealing the plot for the upcoming The Flash/Supergirl musical crossover episode, The CW has released the first look at Darren Criss' villainous Music Meister.

The Glee star will stop by National City for the March 20 episode of Supergirl, although the majority of the crossover's musical magic will occur on the March 21 episode of The Flash. According to the synopsis for the episode, Mon-El and Hank Henshaw show up on Earth-1 with a comatose Supergirl who has been attacked by the Music Meister. The villain then catches Barry by surprise, putting him into a coma as well and dropping him and Kara into an alternate reality where life is a musical. The only way to escape is by singing and dancing their way through.

Criss reunites on the show with his Glee co-stars Grant Gustin and Melissa Benoist, both of whom will perform in the episode. The episode will also provide a showcase for a number of other musically talented Arrow-verse stars, including Supergirl's Tony-nominated tech guy Jeremy Jordan, who can be seen with Criss in the first image from the episode above. (via Entertainment Weekly) Jesse L. Martin, Carlos Valdes, Victor Garber, and John Barrowman will also perform in the episode, which will feature songs written by Crazy Ex-Girlfriend's Rachel Bloom and La La Land's Benj Pasek and Justin Paul. You can watch the first teaser for the episode below.

While we wait for the crossover to premiere, see which two Glee stars were involved in one of TV's biggest behind-the-scenes fights.
