Back To The Future Day: Doc Brown himself has an inspirational message for all humans on 21 October, 2015

'Your future is whatever you make it.'

Christopher Lloyd, now 76, has donned Doc Brown's iconic lab coat and flamboyant shirt once more to deliver a video message to mark 21 October, 2015 or Back To The Future Day, the day the Doc and Marty McFly travelled to in the second film.

Much has been made of the film's verisimilitude, or lack thereof, with real life 2015 (not that this was the creators' intention), but Brown put a more positive spin on the anniversary.

10/21/15! The Future is NOW! Doc Brown has a special message just for you. #BTTF2015

"Great scott! If my calculations are correct, it is now precisely October 21, 2015. The future has finally arrived," he said in the video, posted to the Back To The Future trilogy's official Facebook page.

"Yes, it is different than we all thought, but don't worry - it just means your future hasn't been written yet. No one's has.

"Your future is whatever you make it. So make it a good one."

If clairvoyant movies are what you're after, here's nine that did a better job of predicting the future than BTTF.
