The production is directed by Tony-nominated Liesl Tommy, written by Tony-nominated Chad Beguelin, and features sets by Tony-nominated scenic designer Robert Brill. Jason Michael Webb serves as the musical supervisor and arranger. Puppets for the show were designed by Michael Curry. About 3,500 people auditioned for the initial production, from which the production team selected a cast of over 100 people to put on up to five performances daily.
As part of the transformation of the Hyperion Theater to accommodate Frozen – Live at the Hyperion, the stage was rebuilt. The new additions include a large LED video wall, and large curtains on either side of the stage that serve as a projection surface. The production also includes a large number of mobile sets in addition to the video elements.
Some solo songs like “In Summer” were changed by Webb to ensemble numbers. Some scenes such as Wandering Oaken’s Trading Post and Sauna and characters such as Marshmallow, the ice monster were removed. The theater uses a 2,200-square-foot video wall. For the "Let It Go" sequence, Elsa the Snow Queen stands on top of crystal stairs that rotate out over the crowd.
Confirming a report in February, Disney Cruise Line confirmed that it replaced Toy Story with a Frozen themed production titled Frozen, A Musical Spectacular which debuted on the Disney Wonder beginning November 10, 2016, along with additional enhancements to the ship.
In the Disney California Adventure version of the show, young Anna and Elsa are portrayed by adult actresses, whereas the Disney Wonder version utilizes puppets to portray the sisters up until adulthood.
