GLEE Stars Unite! Darren Criss to Guest on FLASH/SUPERGIRL Musical Episode!

GLEE stars unite! According to TV Line, Darren Criss will reunite with his former GLEE co-stars Grant Gustin and Melissa Benoist in the highly anticipated two-part FLASH/SUPERGIRL musical crossover episode in the role of 'Big Bad Music Meister.'

Executive producer Andrew Kreisberg tells the site, "With our Flash and our SUPERGIRL being GLEE alums, how could we not have them go up against another GLEE favorite like Darren Criss? We have been blown away by his talent over the years and we can't wait to see what he brings to the Music Meister."

As reported last week, the special episode will be broadcast on Monday, March 20 and Tuesday, March 21 at 8/7 each night. The special event programming will begin at the end of Supergirl, with the majority of the musical action taking place during The Flash's portion, aptly titled "Duet."

In addition to Benoist, Gustin and Criss, The CW has confirmed that Broadway vets Jesse L. Martin (Joe), Victor Garber (Dr. Stein), John Barrowman (Malcolm Merlyn) and Jeremy Jordan (Winn); and Carlos Valdes (Cisco) will all partake in the singing portion of the episodes.
