rozen is a Disney media franchise started by the 2013 American animated feature film, Frozen, which was directed by Chris Buck and Jennifer Lee from a screenplay by Lee and produced by Peter Del Vecho, with songs by Robert Lopez and Kristen Anderson-Lopez. Walt Disney Animation Studios' chief creative officer John Lasseter served as the film's executive producer. The original film was inspired by Hans Christian Andersen's fairy tale, "The Snow Queen". Since the film's release in November 2013, the franchise has expanded very rapidly. To date, the franchise includes various Disney theme park attractions, merchandise, video games, books, a Disney on Ice show, a Broadway stage musical and two short animated films. Disney has also confirmed an animated film sequel, and a new book series. In November 2014, TheStreet.com explained that "Frozen is no longer a movie, it's a global brand, a larger than life franchise built around products, theme parks and sequels that could last into the next century". Boxoffice chief analyst Phil Contrino was quoted as saying "it's become massive".
