MUMBAI: Walt Disney Animation Studios is returning to the world of Frozen by featuring Anna, Elsa, Kristoff and the warmth-craving snowman Olaf in a new short film.

Titled Frozen Fever, the film is due in spring 2015. "It's Anna's birthday and Elsa and Kristoff are determined to give her the best celebration ever, but Elsa's icy powers may put more than just the party at risk," reads a plot description for Frozen Fever provided by Disney.

The short- film will reunite the key forces from the original film directors Chris Buck and Jennifer Lee, as well as producer Peter Del Vecho. The film will also include a brand-new song from Robert Lopez and Kristen Anderson-Lopez, the Oscar-winning duo behind Let It Go.

The original movie Frozen released in theaters on 22 November and went on to gross $1.274 billion worldwide. It is the 53rd animated feature in the Walt Disney Animated Classics series. Inspired by Hans Christian Andersen's fairy tale The Snow Queen, the film tells the story of a fearless princess who sets off on an epic journey alongside a rugged iceman, his loyal pet reindeer, and a hapless snowman to find her estranged sister, whose icy powers have inadvertently trapped the kingdom in eternal winter.

Frozen won two Oscars at the Academy Awards including Best Animated Feature and Best Original Song (for Let It Go).
