Speaking to ComicBook.com at press event for A Wrinkle in Time, Lee opened up about her work on the sequel to the surprise hit that was Frozen. On the heels of such massive success, the pressure to deliver another gem is certainly on, but such a mindset is not one Lee will be using to approach Frozen 2.
"I think I can say the number one thing we all held hands on, because we all signed back up again on that one is to not think of the Zeitgeist part of Frozen, because that's not how we made it in the first place," Lee said. "In fact, a lot of people didn't know if the world was interested in the story we had to tell, because it was a musical with two female leads. And we spent it from building character out, and from every inch of what they're struggling with. How can we push them? What are we feeling about them? And we're doing the same thing. I'm really excited about where it's going. I can't wait to share it. But we don't start production until the summer. It's still got its journey. It's still going."
Still, Lee insists writing characters is the same, whether they are animated as they are in her work on Frozen and Wreck it Ralph, or in live-action as will be seen in the upcoming A Wrinkle in Time.
"The writing part of it is the same," Lee said. "The story is a story, is a story. And I don't write animated films for kids. They just happen to be animated. The same with A Wrinkle In Time. It's a family film. But you write it like you would any story. You have to find the truth in the character. The journey is different, but in terms of writing it, the same rules apply, I guess you could say."
Frozen 2 won't arrive in theaters until November 27, 2019 but Lee's work as the scribe on A Wrinkle in Time will arrive in theaters on March 9, 2018.
