The use of sign language (which functions as a kind of gestural choreography) reflects how the teens are unable to meaningfully talk with their parents or teachers, while the adults cannot hear them. Standouts among the cast include Krysta Rodriguez as the sad but fierce runaway Ilse and the spirited Ali Stroker, who may be the first wheelchair-bound actress to appear on Broadway. Oscar winner Marlee Matlin makes a cameo as one of the adults, alongside Camryn Manheim ('The Practice') and the crisp-voiced Patrick Page.
