around them. The experience of both was identical, but the ride enjoyed a very reliable in-service record as a result. If one screen was shut down by a mechanical problem, the other ordinarily remained in service. This increased wait times, but essentially eliminated a complete shutdown of the ride as a whole. Onboard monitor All onboard video for each simulator was played back from a LaserDisc onto a monitor within the vehicle. Currently, Car #8's onboard video still exists and is dated December 10, 1990. It is unknown whether if it's from the Hollywood Version, or the Orlando version of the attraction. Ride film Although Back to the Future creators Robert Zemeckis and Bob Gale had no involvement with the ride, they were consulted as to whether they "got Doc right". They responded with a "yes" and also commented that "it's a great ride". In addition, references were made to a "Zemeckis-Gale diagram" and "Gale-Zemeckis Coordinates". When the ride footage was made, computer animation was not widely used, so all the special effects, sets, and other things in it were actually very detailed miniature sets recorded in stop motion filming. The miniature sets were large, with the replica 2015 buildings as much as half a grown man, and the Tyrannosaurus model being about 7 feet tall. The Institute of Future Technology that the riders crashed into at the end of the ride was actually a model of the Florida version of the building. Cast The film produced for Universal Studios parks in the United States saw Christopher Lloyd and Thomas F. Wilson reprise their roles as Doc Brown and Biff Tannen, respectively. Darlene Vogel starred as Heather, a receptionist for the Institute of Future Technology (IFT). Members of the production crew were also featured in the film. Directors Douglas Trumbull and David de Vos starred as IFT scientists, while Michael Klastorin who was a unit publicist for the second and third films, was an IFT security guard in the ride's film. Frank Welker provided the vocal effects for the Tyrannosaurus. Prior to the ride's debut at Universal Studios Japan, new audio was recorded in Japanese and was dubbed over the original cast. In the Japanese version, Takeshi Aono and Takashi Taniguchi voiced Doc Brown and Biff Tannen, respectively. Chinami Nishimura provided the voice for Heather and Shigeru Ushiyama and Kaneta Kimotsuki voiced the IFT scientists. Crew Ride Film Directed by:
