All that stands in it's way is the two James Cameron Juggernaut's of Avatar and Titanic which with over $2 billion in world takings will be hard to shift.
Frozen has to date done $1.8 Billion of business across the globe and with Titanic on $2.2 Billion it'll find it hard to match that.
Still for an animated film it's just toppled Iron Man 3 from the number 3 spot with ease and Disney have their biggest film for a number of years on their hands, with merchandise takings as well this has been massive.
