The short is set to feature a new original song by Robert Lopez and Kristen Anderson-Lopez, who won an Academy Award for Let It Go and are working together again for the first time since collaborating on that is Frozen.

Both Frozen directors Jennifer Lee and Chris Buck are returning to direct the short.

It’s not yet confirmed how fans will get to see Frozen Fever but it is believed is might be shown ahead of Cinderella which opens March 13, 2015 (in US and Canada).

Two other shorts have been confirmed by Disney. One is titled Feast and concerns a Boston terrier puppy called Winston, who shares meals under the table with his owner. This is being shown with Big Hero 6, which is due later this year, on November 7, 2014 (in US and Canada).

The other is Pixar’s Lava and will feature a Hawaiian volcano singing Somewhere Over the Rainbow and will be screened with Inside Out, which has a release due on June 19, 2015 (in US and Canada).

Below is a clip from Disney’s Frozen where Elsa, whose secret powers have just been revealed, flees Arendelle and unleashes her magic, creating a breathtaking ice palace. The song is performed by the voice of Elsa, Idina Menzel, “Let It Go” is an original song by Kristen Anderson-Lopez and Tony Award®-winner Robert Lopez.
