"Frozen" surpassed the $1 billion mark over the weekend, putting it on track to becoming the highest-grossing animated film of all time. In North America, the Disney flick has earned $388.8 million. It has pocketed an additional $611.5 million globally.

The movie, which won "Best Animated Film" at Sunday's Oscars, is still in theaters around the world and is opening in Japan next week.  It's on the heels of the 2010 animated film "Toy Story 3," which grossed a total of $1.06 billion.

"Frozen," which features the voices of Kristen Bell and Idina Menzel, is the highest-grossing animated non-sequel film. It centers on fearless optimist Anna, who goes on a quest with rugged mountain man Kristoff and his loyal reindeer Sven to find her sister Elsa, whose icy powers have trapped the kingdom of Arendelle in eternal winter.

"Frozen" songwriting duo Robert Lopez and Kristen Anderson-Lopez also won "Best Original Song" for "Let It Go" at the Academy Awards.

The "Frozen" soundtrack is also performing well. It has spent five weeks at number one on the Billboard charts.
