Why a DeLorean for Back to the Future?
The original script for Back to the Future was much different from the final movie. One such aspect was the time machine itself which, at one time, was a refrigerator. But concerns arose over the use of a refrigerator, as it was feared that children playing with abandoned appliances might close themselves inside and become trapped. (Of course, that was before they switched to new latches that could be pushed open.) So, that idea was nixed. Instead the decision was made the use a car, so that Doc Brown could be mobile during his travels through time. Bob Gale and Robert Zemeckis (writers of BTTF,) have also said they thought the DeLorean was perfect for the joke when Marty crashes into the barn in 1955, and the farmer says it looks like “an airplane… without wings.”
