See how far we've come since Doc and Marty McFly were sent to the future in Robert Zemeckis’ 'Back to the Future Part II.'
For those unfamiliar with Robert Zemeckis’ Back to the Future Part II, today — October 21, 2015 — is the day that 1985’s young Marty McFly was zapped to in order to prevent his son from participating in a robbery with the grandson of bully Biff Tannen. Of course, no time-travel adventure comedy would be complete without a considerable amount of butterfly effect blunders.
