It’s only apt that when two former Glee stars are coming together for a superhero crossover that the villain is also a former Glee cast member.
Grant Gustin (The Flash) and Melissa Benoist (Supergirl) are going to be joined by Darren Criss.
Criss has been cast as the melodious bad guy, Music Meister.
Grant Gustin revealed that he’s been trying to get Cross a role on The Flash since it began and now he’s got that opportunity. Neil Patrick Harris has previously brought this character to life on the animated series Batman: The Brave and the Bold so Criss has some big shoes to fill. I’ve got no problems believing that he’ll be able to fill them
The musical crossover starts at the end of Supergirls’s March 20th episode and carries on over into The Flash’s March 21st episode. Directed by Dermott Downs, the highly anticipated hour will feature musical performances from Gustin, Benoist, Jesse L. Martin, Legends of Tomorrow‘s Victor Garber, Carlos Valdes, Jeremy Jordan, and Arrow alum John Barrowman, who currently stars on Legends of Tomorrow.
