‘Supergirl’/’The Flash’ Musical Crossover Continues In 3.17 Synopsis

Supergirl The Flash Musical CrossoverThe CW released the official description today for the seventh episode of The Flash Season 3 titled “Duet”. This will mark as the second part to the upcoming musical crossover with Supergirl, which will start on Monday, March 20 in the episode’s final minutes.

DARREN CRISS (“GLEE”) GUEST STARS AS THE MUSIC MEISTER IN THE FLASH AND SUPERGIRL MUSICAL CROSSOVER – Barry (Grant Gustin) and team are surprised when Mon- El (guest star Chris Wood) and Hank Henshaw (guest star David Harewood) arrive on their Earth carrying a comatose Supergirl (guest star Melissa Benoist) who was whammied by the Music Meister (guest star 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, complete with singing and dancing, to the end. Dermott Downs directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Aaron Helbing & Todd Helbing (#317). Original airdate 3/21/2017.

It was announced that Crazy Ex-Girlfriend star Rachel Bloom has written a song called “Superfriends” as one of the original songs that we will be getting in the crossover. La La Land songwriters, Benj Pasek and Justin Paul, have also contributed with a song for the event as Grant Gustin will be singing “Runnin’ Home to You”. Glee’s Darren Criss will be playing the villainous Music Meister.

The musical event will feature stars from all four CW DC shows with Barry Allen (Grant Gustin), Kara Zor-El (Melissa Benoist), Joe West (Jesse L. Martin), Cisco Ramon (Carlos Valdes), Martin Stein (Victor Garber), Malcolm Merlyn (John Barrowman) and Winn Schott (Jeremy Jordan) that will all be making singing appearances. Martian Manhunter (David Harewood) and Mon-El (Chris Wood) will show up in non-singing capacity. Gustin and Benoist have worked with Criss previously as all three of them come from the FOX musical comedy-drama Glee that ran for six seasons.

The Flash airs on Tuesday nights at 8/7c on The CW. Make sure to check back at Heroic Hollywood after every single episode of Season 3 for our weekly reviews.
