he animated adventures of a mouse, Basil of Baker Street, called upon to search for a toymaker, Flaversham, who has been kidnapped to make a robot replica of the queen for the evil Ratigan. Basil, aided by the intrepid Dr. Dawson, helps the toymaker's daughter, Olivia, search for her father. They foil Ratigan's plot and eventually save the queen. After a four-year period of story development, animation took just over one year to complete. This remarkably short production span was possible due to new efficiencies in the production process (such as video tests and computer-assisted layouts and graphics), and an increased emphasis on story development prior to the start of production. 125 artists were involved in making the film. An innovative application of computer technology can be seen in the climactic scene where Basil faces Ratigan in a final confrontation inside the turning and thrashing gearworks of Big Ben. The 54 moving gears, winches, ratchets, beams, and pulleys were literally drawn by the computer, and created a unique background for the characters, which had been animated in the usual way. The film was rereleased in theaters in 1992 under the title "The Adventures of the Great Mouse Detective." Released on video in 1992.
