In July 2010, film news site Total Film made a fake image for the clock on the iconic Back to the Future car, make it appear that July 5, 2012 was the date in the future that Marty and Doc traveled to in the second installment of the series. The correct date from the film is October 15, 2015.
According to Total Film, they made the image as a goof to cover their tracks after they tweeted about it incorrectly. They didn't realize that it would take off with a life of its own. I remember seeing the image passed around two years ago, and then being disappointed to discover it was fake.
You may have seen an image with today's date floating around Facebook and Twitter. Some merry prankster is reliving the glory of the Great Back To the Future Day Panic of 2010 and trying it out again.
Will this happen again before 2015? After? Good grief, stop toying with our love of the greatest hoverboard film in cinema history!
