Director, Robert Zemeckis revealed in the “Making Of” documentary thatthe original script planned a different time setting, with Young Biff receiving the almanac in the 1960s, rather than 1955.
Zemeckis revealed that his original draft ofPart II’s script included segments with Marty finding his mother, Lorraine, as “a flower child, and she’s protesting the war in Vietnam,” and landing himself in jail. Zemeckis stated thatco-writer, Bob Gale read the draft and said that while he felt it was okay, he felt the sequel could work better if the DeLorean would go right back into the original’s events, resulting in the script being rewritten. The sequel’s original 1960s setting would have offered a different timeline for audiences and separated the story from the events of the first movie.
