SpongeBob SquarePants and his gang of undersea misfit pals are coming to Broadway's Palace Theatre this winter in a new musical unlike anything audiences have ever seen. Director Tina Landau has completely reimagined the animated world of Bikini Bottom for the stage, while book writer Kyle Jarrow has crafted a story that he describes as "Armageddon meets Our Town." As for the score? It's written by some of the most iconic musicians of this generation: Aerosmith, Cyndi Lauper, and John Legend, among them. What does it take to transform an animated television series into a Broadway musical? Landau, Jarrow, and stars including Ethan Slater and Lilli Cooper, fill us in.
