The show also features the most magical and expensive cast ever. Sara Bareilles and her enchanted vocal chords star as Ariel, and Rebel Wilson plays the evil sea witch Ursula. The rest of the cast includes John Stamos as Chef Louis, Darren Criss as Prince Eric, and Joshua Colley as Flounder. Tituss Burgess will be playing Sebastian the crab, and Norm Lewis will be featured as King Triton, both reprising the roles they originated on Broadway.
