Laserdisc was the first optical storage medium, initially licensed, sold, and marketed as MCA DiscoVision. The technology behind the laserdisc were the foundation for future optical disc technology, including the compact disc, DVD, and Blu-ray disc.
In 2015, large packs of laserdiscs were present, along with packs which may have been DVDs, in the alleyway where Emmett Brown and Marty McFly landed the DeLorean time machine before executing their plan to clear Marty McFly Jr.'s name.
Whether these discs were being thrown away or shipped to be sold is unclear. Some of the discs may also have been compact discs, which were the same size, and were just starting to replace vinyl records in 1985.
Behind the scenes
- The "To Be Continued" screen was only added to the home release of Back to the Future. It was not originally included in the theatrical release, as a sequel was not originally planned.
- The "Coming Summer 1990" screen was removed from the home release of Back to the Future Part II. However, it was retained on the 2010 and 2015 home releases of the film trilogy.
