Disney’s Frozen was the biggest animated movie that had ever come out when it was released.
In the case of Frozen however, they made an exception, and Frozen II took over the top spot as the highest grossing animated film ever.
It’s the sort of movie that would have spawned an automatic sequel were it any other film.
While the second movie brought back familiar characters, it changed a great deal, and Kristen Bell thinks one particular aspect of that change, the way the story matured, was a big success.
