Hercules is a 1997 American animated musical fantasy comedy film produced by Walt Disney Feature Animation for Walt Disney Pictures. The 35th Disney animated feature film and the eighth animated film produced during the Disney Renaissance, it is loosely based on the legendary hero Heracles (known in the film by his Roman name, Hercules), the son of Zeus, in Greek mythology. The film was directed by John Musker and Ron Clements, both of whom also produced the film with Alice Dewey Goldstone. The screenplay was written by Musker, Clements, Donald McEnery, Bob Shaw, and Irene Mecchi. Featuring the voices of Tate Donovan, Danny DeVito, James Woods, and Susan Egan, the film follows the titular Hercules, a demigod with super-strength raised among mortals, who must learn to become a true hero in order to earn back his godhood and place in Mount Olympus, while his evil uncle Hades plots his downfall.
Development of Hercules began in 1992 following a pitch adaptation of the Heracles mythological stories by animator Joe Haidar. Meanwhile, Clements and Musker re-developed their idea for Treasure Planet (2002) following the critical and commercial success of Aladdin (1992). Their project was removed from development in 1993, and Musker and Clements joined Hercules later that same year. Following an unused treatment by Haidar, Clements and Musker studied multiple interpretations of Greek mythology before abandoning Zeus's adulterous affair with Alcmene. The project underwent multiple story treatments and a first script draft was inspired by the screwball comedy films of the classic Hollywood era and popular culture of the 1990s. During production, McEnery, Shaw, and Mecchi were brought on board to revise Musker and Clements' script. British cartoonist Gerald Scarfe was recruited as production designer and produced over seven hundred visualization designs of the characters. Research trips to Greece and Turkey provided inspiration for the background designs. Animation for the film was done in California and Paris.
