1. Nobody Expected the Film's Monster Success: The team behind "Frozen" always knew that the film was special, but nobody expected it to become the fifth highest grossing film of all time. "It took on a life of its own," Del Vecho marveled. "It's been very exciting!"

3. ... But It Built on Old Themes: Yes, "Frozen" was a departure from previous Disney animated films, but there were familiar tropes, too. However, the film dealt with them a little differently. "We did want to turn them on their heads -- the love at first sight, or the [concept of] Prince Charming," he said. "We kept asking ourselves, 'What movie do we want to see today?' and ... we did not set these girls up on a pedestal. They have real issues and real problems just like we all do in real life. [We wanted to] make them real and relatable."

4. "Let It Go" Created the Movie's Theme: "It was such an empowering song that we ended up rewriting quite a bit of the movie to make that song and theme fit," Del Vecho said of the movie's feel-good anthem. "What I love most about it is everyone who hears it comes up to me and has a different of interpretation of why it touches them."

5. You'll Get a Sneak Peek at a Future Project: While work on the "Frozen" franchise is still ongoing (there's a Broadway show in the works and a "Frozen" story arc coming to "Once Upon a Time" on ABC),") Walt Disney Animation Studios is currently putting the finishing touches on its newest film, "Big Hero Six." The ABC special will feature the debut of a scene from the film. "We're really hitting our stride and telling real, believable, heartfelt stories," Del Vecho said.
