Disney has confirmed the new film will see the return of all the main original characters.
The plot for the film explains: “In Frozen Fever, 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.”
What’s more, it’s also been confirmed that the eagerly awaited short film will feature a song from Oscar winners Robert Lopez and Kristen Anderson-Lopez, who were behind theme song, Let It Go, while Jennifer Lee and Chris Buck are set to return to directing duties.
The short was announced during a US television special about the film called The Story of Frozen: Making a Disney Animated Classic, which aired in the US on Tuesday night.
Earmarked for spring 2015, no details about how the special will be shown were announced. It is possible that it might be broadcast on US network ABC like Toy Story spin-off short, Toy Story of Terror which aired last year.
Frozen became the highest-grossing animated film ever, earning $1.275bn worldwide and passing Disney classics, Toy Story 3 and The Lion King.
Meanwhile, it was reported earlier this week that Disney has been offered $20.2m by the Australian government to film Pirates of the Caribbean: Dead Men Tell No Tales in the country.
Variety.com reported that George Brandis, the Australian Federal Arts Minister, agreed the lucrative deal after lengthy negotiations with Disney.
Brandis explained: “The government is pleased to agree to Disney’s request to enable earlier funding to be repurposed for the production of Pirates of the Caribbean 5.
“Any decision to film productions in Australia is a commercial matter for Disney.”
