Blu-ray is a digital optical disc storage format that was designed to supersede the DVD format. Because it is capable of storing large amounts of data, it is capable of storing videos in high definition video resolution.


In 2015, large packs of discs which may have been Blu-ray discs were present, along with packs of what were possibly DVDs and laserdiscs, in the alleyway where Dr. 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[]

  • Although prototype players were being released as early as 2003 in Japan, Blu-ray players weren't officially available until 2006. It was not until 2010 that the long-awaited Blu-ray release of the Back to the Future trilogy took place. The trilogy was later re-released on Blu-Ray in 2015, with a short film entitled Doc Brown Saves the World.
