Any new scoop on the Once Upon a Time musical? — Lisa
For starters, the musical is not a one-off. “The first thing people should understand is the musical is not a standalone — so it will be continuing the story,” EP Edward Kitsis says. “It’s not like, ‘Oh, we’re taking a break from all the intensity to do a musical!’ It is absolutely going to further what we’ve been doing and it sets up the finale.” The second thing you should know: “We’re doing all original songs,” Kitsis says. “You’re going to see a wide-range of people singing from regulars to cameos to people you wouldn’t expect.” EP Adam Horowitz adds: “You’ll probably see more people singing than you’d expect, and some fun in how it’s done.” Among those surprising faces also singing: Granny, Grumpy, Gepetto and Henry! As for the main cast, I can share that most of them will be singing and performing more than one song.
