There is a tweet going round – i dont know who started it, but they seem to have gotten the 25 year anniversary of Back To The Future 1 confused with the fictional date of Doc Browns travel to the future:
In ‘Back to the Future’, Doc sets clock in the DeLorean to a day 25 years in the future. Today is that day.
It is escalating like wildfire:
THIS IS INCORRECT!!!!!
From the BTTF wiki:
Doc Brown of Timeline 1 had always dreamed of seeing the future, looking beyond his years, seeing the progress of mankind, and seeing who would win the next twenty-five World Series. On October 26, 1985, he was preparing to set the time circuits to 2010, but the Libyans found him before he could input the new destination time. Doc Brown of Timeline 2 preferred going 30 years ahead, and traveled to 2015 after dropping Marty off at Lyon Estates.
