Pocahontas (1995 film) [SEP] Introduction
The voice cast stars Irene Bedard and Mel Gibson as Pocahontas and Smith, respectively, with David Ogden Stiers, Russell Means, Christian Bale, Billy Connolly and Linda Hunt providing other voices. The score was written by Alan Menken, who also wrote the film's songs along with Stephen Schwartz. After making his directorial debut with "The Rescuers Down Under" (1990), Gabriel conceived the film during a Thanksgiving weekend. The project went into development concurrently with "The Lion King" (1994) and attracted most of Disney's top animators. Meanwhile, Disney studio chairman Jeffrey Katzenberg decided the film should be a serious romantic epic in the vein of "Beauty and the Beast" (1991), in hope that, like "Beauty", it would also be nominated for the Academy Award for Best Picture.
