It’s a television law: If you cast actors who once appeared on Glee as the leads in your series, at some point your series is going to have to do a musical episode. On March 21, The Flash (starring former Glee warbler Grant Gustin) will honor this sacred rule by crossing over with Supergirl (starring Glee alum Melissa Benoist) for a musical episode called “Duet.” After Music Meister (played by another Glee vet, Darren Criss) puts Barry and Kara under his musical spell, viewers will watch them take a dreamy, musical adventure featuring many familiar faces. Click through to see the stars in the glamorous alternative reality.
The Flash‘s musical crossover with Supergirl, “Duet,” airs Tuesday, March 21 at 8 p.m. on The CW.
