Transcript for 'Frozen' musical is about 'empowered women'
with us. The first look at "Frozen" on Broadway. ABC's -- we know we had to play that. ABC's juju Chang got a sneak peek. Here's a look. ??? For the first time in forever ??? Reporter: The love story about two sisters, Elsa and Anna, a familiar fairy tale and yet you've never seen "Frozen" like this. ??? All ends tomorrow so it has to be today ??? It's not just watching a movie on stage. It's two living breathing women who aren't just Disney princess. That's the thing about the princesses I feel like. I feel like this is a story about two women who happen to be princesses as opposed to a story about princesses who happen to be a sister. Reporter: Kristin Anderson Lopez and first ever double egot winner Bob Lopez are the minds behind the music that launched the highest grossest animated film of all time. ??? Let it go ??? ??? let it go ??? Reporter: Now creating nearly a dozen new songs for the more grown up broad way version. When we looked at turning this movie into a full length two-hour musical, we knew we had to go a lot deeper, get a lot more sophisticated and add a lot more music. Also we had practical considerations too because on stage you can't do a close-up and you can't do a big action sequence with cars and explosions and reindeer and sleds falling off cliffs and stu like that and wolves, so you need to find musical solutions to all those things that worked in the film that couldn't work as well on stage. ??? We wrote a song called "Dangerous to dream" which is Bobby's favorite song, I would say. Reporter: Nearly tripling the musical set list meant creating a new power ballad "Monster" for Elsa. ??? If I'm a monster it's true ??? Reporter: Shakespearean themes evoked by a veteran shakespearean director. In the second half we have this new number "Monster" and Elsa comes on and has a really deep debate with herself about whether she's a monster who should even be here. ??? I will not be a monster ??? That was a per kt example of a song that has an extraordinary arc within it where you start one place and the debate that goes on leads you to another and out you come with an audience triumphantly moving forward. To be or not to be and, of course, there's olaf. He will low. How are you? I don't know which hand to shake. Just as charming and lovable as he was in the film. Hey, oh, I love it even more. Reporter: But ultimately this modern story of two spring sessions delivers a message that feels particularly timely. This is about empowering women, a princess in pants and about finding your power and nuanced three-dimensional women dealing with leadership, love and their own relationships. Reporter: For "Good morning America," juju Chang, ABC news, New York. Right. That looks like it's going to be a lot of fun. "Frozen" does open tonight on Broadway and you can see more on "Nightline" with juju Chang. Coming up, everybody, that
