As speculated the instant the two-part Supergirl/The Flash musical crossover was announced last summer, the superfriends will indeed battle The Music Meister, executive producer Greg Berlanti confirmed on Sunday at the Television Critics Association winter press tour.
And though Neil Patrick Harris voiced the DC Comics villain in the Batman: The Brave and the Bold animated series — and thus has been speculated/hoped to assume the live-action role — The Music Meister has not yet been cast, Berlanti said.
“We’re certainly huge fans of [Harris],” showrunner Andrew Kreisberg later added, “and as the casting process proceeds, we’ll see what happens.”
CW president Mark Pedowitz told TVLine on Sunday morning that he was just about to see the script for the musical two-parter, adding: “We’re very excited about it. There’s great musical talent on both shows,” including but not at all limited to series leads/Glee alumni Melissa Benoist and Grant Gustin.
