Narrating the scene, Marshall called it “the most challenging musical sequence I’ve ever created.” This is the latest episode of our Anatomy of a Scene series, where film directors reveal the secrets of making movies and comment on the craft of movie-making. #thelittlemermaid #robmarshall #hallebaily #filmmaking
