Parents be warned - there’s a sequel to Disney’s mega hit Frozen on the horizon, and it features an even catchier tune set to drive us all mad. Frozen Fever is a seven-minute short film which reunites the cast, characters, directors and even songwriters of the original 2013 movie, and will be screened ahead of Disney’s Cinderella (that hits cinemas on March 13 in the US and April 3 in the UK). ‘If history is any indicator, kids will go nuts,’ Actor Josh Gad - voice of Olaf the snowman - tells USA Today, about the catchy new song. Husband and wife duo Robert Lopez and Kristen Anderson-Lopez - who were responsible for the Oscar-winning song Let It Go - have teamed up again to create another earworm for fans.

One of the film’s directors - Jennifer Lee - previously apologized to parents for the sing-a-long-friendly hit. Lee told The Hollywood Reporter: ‘A year ago, I’d meet people who, when they found out who I was, they’d say, “Oh, we love the songs! We sing them all the time.” Now they’re like, “Yep, we’re still listening to those songs. I’ve gone from, “Thank you,” to, “Sorry!”‘.

Speaking about the new mini-movie, co-director Chris Buck reveals: ‘It’s another side of Elsa the audience hasn’t seen before and we hadn’t really played with in the original feature.’

Buck and Lee have reunited as directors of the project, which sees Anna’s plans to put on a birthday party for Elsa get ruined, after the snow queen catches a cold. But of course, it is not a common cold the for the magical character.

Lee reveals: ‘Elsa doesn’t get a cold in the usual way. She’s special. Surprising things occur that wreak a little havoc.’

Actor Gad added of the story: ‘We continue this story of these two sisters, who only had each other growing up together. They are still supporting each other. That’s what this is about.’

Both Kristen Bell and Idina Menzel are also back on board, voicing the roles of Princess Anna and Princess Elsa respectively.

The original movie took over a billion dollars at the global box office, and is the most successful animated movie of all time, so it’s no wonder the filmmakers have reunited for the project.

The news of the short-film was first revealed in September last year, and there has been continued speculation that Disney is working on a proper full-length sequel to the movie. However, the studio is yet to confirm any official plans.
