According to co-director John Musker, adapting the fairy tale “The Frog Prince” by the Brothers Grimm into an animated feature film had been a subject at Walt Disney Animation Studios for 18 years. The project was repeatedly shelved because the studio was unsuccessful in creating a version with which they were satisfied. Disney bought the rights to The Frog Princess, a novel by E. D. Baker that is based on the fairy tale, in 2006. Co-directors Ron Clements and Musker were then hired to lead the studio in yet another attempt at adapting the fairy tale, choosing 1920s New Orleans as its setting. Although originally conceived as a computer-animated film, Clements and Musker fought for The Princess and the Frog to be traditionally animated.
