Queen Diana (formerly Princess Diana) was the Queen of the United Kingdom in 2015.
According to the Newsline column on the front page of the October 22, 2015 issue of USA Today, she was to visit Washington, D.C. "tomorrow and the capital prepares". The visit was also announced in the FROM THE CAPITOL [sic] box-out in the top right-hand corner.
In this timeline, Diana was still alive and still married to Charles, Prince of Wales. Queen Elizabeth II had died and Charles inherited the throne (though it remains unclear as to whether his regnal name, or reign name, was Charles III or George VII), thus Diana had become Queen.
Behind the scenes
- In actuality, Princess Diana died in a car accident on August 31, 1997 in France, long after these predictions were made. Additionally, it is uncertain whether she would have even been Queen. She and Prince Charles divorced in 1996, and were having marital problems as early as 1987. On top of everything, Elizabeth II was still alive in 2015.
- Bob Gale jokingly said (on the audio commentary) that he had no idea about the 1997 death of Princess Diana when he wrote the script in 1989, but said he probably should have considered that as a possibility.
- Another sign of things nobody could have predicted is when, in 2015, Lorraine McFly changes the channels on the scene screen from a garden, to a tropical beach, to a nighttime city scene that includes the Twin Towers of the World Trade Center, which were destroyed in 2001. However, it is possible that Lorraine was watching a past documentary about the city of New York.
