Five years ago, movie fans celebrated Back to the Future Day. October 21, 2015 was the date that Doc Brown, Marty McFly and Jennifer Parker arrived in future Hill Valley at the start of Back to the Future Part II. The much-loved 1989 sequel imagined a 2015 with flying cars and hoverboards – sadly a future that never came to be.
Nevertheless, an intriguing fan theory argues that Marty McFly changed the past, thus creating the 2015 without those inventions in our timeline.
Reddit user kravatz argued: “In the second Back To The Future movie, Marty travels to a very different 2015 from ours.
“There Marty learns that Future Marty’s life is not that great and that it is a consequence from a car accident he had back in 1985.
“When Marty returns to 1985 in the third movie and takes Jennifer for a ride in the new truck, he has learned not to lose his temper when someone calls him a chicken and with knowledge of the future he doesn’t race Needles.”

Gale replied: “Y’know we kick around things every once in a while.
“But look, the bottom line is, doing Back to the Future without Michael J Fox is just not something that we want to see; I don’t think anybody wants to see.
“To create a future version of Marty McFly where he has Parkinson’s disease…that really doesn’t sit right.”
Fox has lived with Parkinson’s since 1991 and has been semi-retired from acting for 20 years as his symptoms have worsened.
Gale continued: “We’ve all seen sequels where they did one too many, or two or three too many.
“We just said, ‘Y’know what, these movies are great the way they are, let’s just leave them alone.’
“Because the conversation then always becomes, ‘Why did they make another one?!’”
