Back to the Future (1985) Movie script (Copy) Production draft Revised October 21nd, 1984 Directed by Robert Zemeckis Written by Robert Zemeckis and Bob Gale Marty McFly, a typical American teenager of the Eighties, is accidentally sent back to 1955 in a plutonium-powered DeLorean "time machine" invented by a slightly mad scientist. During his often hysterical, always amazing trip back in time, Marty must make sure his teenage parents-to-be meet and fall in love to get back to the future. Will be very well packed and will be sent with a tracking number.
