Jag har inte hittat någon aning varför manuset säger 1:15 men vi kan utgå från några orsaker i universum
Utanför universum, Michael J Fox var bara fri att arbeta nätter
The only reason Michael J. Fox was even able to appear in Back to the Future was that his Family Ties co-star Meredith Baxter was getting ready to give birth to twins. The show’s schedule had to be changed as a result, and Fox was allowed to work part-time on Back to the Future.
During the nine weeks of shooting, the film crew mostly got to work with Fox only at night, as he would spend most of his days in Paramount rehearsing that week’s episode of Family Ties. In the evening, a driver would take him to whatever location Back to the Future was filming at that night. Fox would work on the movie until early in the morning, when he would be taken back home to catch a couple of hours of sleep. Then, another driver would wake him up, make him a coffee and take him to Paramount for another day of rehearsing.
