Disney’s “Frozen,” directed by Jennifer Lee and Chris Buck, won the Oscar for animated feature Sunday.

Loosely based on the Hans Christian Andersen fairy tale “The Snow Queen,” the film centers on Anna (voiced by Kristin Bell) and Elsa (voiced by Idina Menzel), sister princesses of Arendelle. When Elsa accidentally unleashes an eternal winter upon Arendelle after an emotional outburst at her coronation, she flees the kingdom and Anna sets off to search for her in order to save their homeland and mend their relationship. Jonathan Groff, Josh Gad and Santino Fontana also lend their voices to the film.

This was the first nomination for Jennifer Lee, who also wrote the screenplay for the film. Chris Buck was previously nominated for 2007’s “Surf’s Up.” “Get a Horse!,” which accompanied “Frozen” in the theaters, was also nominated in the animated short category.
