The Rescuers Down Under has three characters from the first movie: Bernard, Bianca, and the Chairmouse. All of them are played by the same actors as in the first movie.
Bob Newhart as Bernard, a male grey mouse; the United States representative of the Rescue Aid Society. Mark Henn, Ed Gombert, and Anthony DeRosa were the supervising animators for Bernard.
Eva Gabor as Miss Bianca, a female white mouse; the Hungarian representative of the Rescue Aid Society. Mark Henn and Ed Gombert were the supervising animators for Bianca. This is Gabor's final film role: she died in 1995. Disney would have made a third movie, but due to that, all Rescuers movies were cancelled. Neither reviving the third movie nor replacing the voice of Miss Bianca could work. This might be the last movie of the series.
John Candy as Wilbur, a comical albatross; named after Wilbur Wright. He is the brother of Orville, the albatross who was in the first movie. Nik Ranieri was the supervising animator for Wilbur.
Frank Welker as Marahute, a giant Golden Eagle, Joanna, a comical goanna and McLeach's pet who acts to scare her captives and additional special vocal effects. Glen Keane was the supervising animator for Marahute.
Bernard Fox as Chairmouse, the chairman of the Rescue Aid Society. Will Finn was the supervising animator for Chairmouse. Fox also voices Doctor Mouse, the supervisor of the surgical mice who examine Wilbur when he is injured.
The Rescuers Down Under was released alongside The Rescuers on Blu-ray in a "2-Movie Collection" on August 21, 2012 to commemorate the first movie's 35th anniversary.[2]
