'The Story of Frozen': Five crazy facts you may not know about 'Frozen'

On the ABC special "The Story Of Frozen" we got a behind-the-scenes look at the making of the hugely popular Academy Award-winning film. Here are five crazy facts you may not know about 'Frozen.'

First up, can you believe the hit song "Do You Wanna Build a Snowman" was almost taken out of the film?

Secondly, the film took over 70 years to make. More time and energy was put into the movie than most people could realize, but it was definitely well worth it, as Variety pointed out:

"For those unfamiliar with how labor-intensive the genre is, it's stated right off the bat that the movie – now the highest-grossing animated film of all time –- employed 600 people for 2 1/2 years."

That's a pretty crazy third fact. At number four, as Good Morning America noted, the hyper-successful song "Let It Go" actually changed Elsa's character quite a bit -- causing the team to rewrite much of the film.

"When I first came on, they had made her this blue character, spikey hair, it seemed like she was quitesential evil queen," actress Idina Menzel said.

Last but not least, According to CinemaBlend, the songwriting duo for "Frozen" is actually a husband and wife team: Robert Lopez and Kristen Anderson-Lopez. Awww. The couple won an Academy Award for "Let It Go," surprising absolutely no one.
