Los Angeles (AFP) - Fans of hit movie "Frozen" who can't let it go can reunite with Elsa, Anna and Olaf this weekend in a short film being released around the world.
The most successful animated film in history, "Frozen" has already raked in a cool $1.3 billion in earnings since its release in 2013, picking up two Oscars and a clutch of other awards along the way.
Disney this week confirmed that a sequel was in the works, delighting fans who flocked to the first film in droves and sending shares in the studio soaring.
Before then however comes the featurette "Frozen Fever," offering fans the chance to reacquaint themselves with the film's characters -- albeit for only seven, brief minutes.
The film is being released alongside Disney's live action feature film "Cinderella," which opens in North American theaters on Friday.
The short revolves around the problems that ensue when Elsa comes down with a heavy cold while a birthday party for her sister Anna is being prepared.
"It's a fun way to relive the characters because we love these characters as much as the fans do, it's a way to almost say thank you," producer Peter del Vecho told AFP.
"The whole idea of the short was we want to have fun with these characters, we want to have humor for Elsa, something she didn't get to have in the movie.
"In seven minutes you can bring a lot of joy. It's sort of a celebration."
The "Frozen" creative team began work on the featurette a year ago following the runaway success of the film, inspired by Hans Christian Andersen's "The Snow Queen."
The short feature also sees the voices of Elsa and Anna -- Idina Menzel and Kristen Bell -- reunite on a new song "Making Today a Perfect Day," with the daunting task of trying to match global hit "Let It Go."
