It sounds like a few more Frozen songs are in the works. Disney announced Friday the hit film’s songwriting duo, Robert Lopez and Kristen Anderson-Lopez , will be working on songs for its stage musical version. Jennifer Lee , the film’s co-director and screenwriter, will pen the book. Thomas Schumacher , president and producer, Disney Theatrical Productions, said in a statement, “Disney Theatrical is working on a stage adaptation of the animated film Frozen. It will come as no surprise that the EGOT-winning Broadway veteran Robert Lopez and the Oscar and Grammy winning Kristen Anderson-Lopez, who wrote the indelible songs for the film, will be working on the show and that Oscar winner Jennifer Lee, co-director and screenwriter of the film, will be working on the book of the stage version.”
