This was the first 100% digital feature film ever made. The animation and backgrounds were done traditionally but all of the coloring, many effects and the final film printing was all done digitally. This was the first film produced with Disney's Academy Award Winning "CAPS" production system.
In the original Rescuers film, the albatross Orville was voiced by Jim Jordan who died two years before this film released. The character was replaced with Orville's brother Wilbur, voiced by 'John Candy (I)'. This is a reference to the Wright brothers, Orville and Wilbur, the inventors and pilots of the first functional airplane.
On its initial release, this film was preceded by the Mickey Mouse short subject The Prince and the Pauper (1990). Interestingly enough this was only the second Mickey Mouse short made since the 1950s, with the first being Mickey's Christmas Carol (1983) which was made to accompany the 1983 re-release of The Rescuers.
