Consider the question. Direction was by Francesca Zambello, making her Broadway debut, with choreography by Stephen Mear. Scenic design was by George Tsypin, costumes by Tatiana Noginova and lighting by Natasha Katz. The original cast featured newcomer Sierra Boggess in the title role of Ariel, Sean Palmer as Prince Eric, Brian D'Addario and Trevor Braun alternated as Flounder, Norm Lewis as King Triton, Sherie Rene Scott as Ursula, Tituss Burgess as Sebastian, Tyler Maynard as Flotsam, Derrick Baskin as Jetsam, Jonathan Freeman as Grimsby, and John Treacy Egan as Chef Louis. Notable replacements included Faith Prince as Ursula and Drew Seeley as Prince Eric. The production closed on August 30, 2009, after 50 previews and 685 performances. Thomas Schumacher, producer and president of Disney Theatrical Productions said, "it would be fiscally irresponsible to our shareholders to risk operating losses with such a big show in the historically challenging fall months. We are closing the Broadway production to concentrate on the long future life of this title."
