Walt Disney Animation Studios is revisiting Arendelle!
Frozen Fever, a short film due in Spring 2015, will reunite key players from 2013's surprise smash hit Frozen. Directors Chris Buck and Jennifer Lee will return, in addition to producer Peter Del Vecho and songwriters Kristen Anderson-Lopez and Robert Lopez, who won the Academy Award for "Let It Go."
It's unknown if Kristen Bell (Anna), Josh Gad (Olaf), Jonathan Groff (Kristoff) and Idina Menzel (Elsa) will reprise their voice roles—but given their characters' popularity, it seems highly likely they'll come back.
To date, Frozen has earned $1.27 billion worldwide and is the most successful animated film of all time.
Frozen Fever's plot is simple: "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," the studio said.
Walt Disney Animation Studios didn't specify which feature film Frozen Fever will accompany, but a likely candidate is the live-action Cinderella film on March 13 starring Cate Blanchett and Lily James. Tomorrowland, starring George Clooney, and Inside Out, featuring Amy Poehler, are also out in 2015.
Meanwhile, Anna and Elsa will be headed to ABC's Once Upon a Time. The show returns Sept. 28.
