An old fan debate about Back to the Future and one of its perceived plot holes was resuscitated via Twitter this week, a viral sensation which drew BTTF screenwriter Bob Gale into the debate to settle the question himself.The debate — reignited by the trending list “5 Perfect Movies” — was about why Marty McFly’s parents didn’t recognize him as Calvin Klein, the teen who engineered their romance back in the ’50s, when he returned home to the 1980s. Surely, George and Lorraine McFly would recognize their son Marty as their high school acquaintance Calvin?
Guardians of the Galaxy director James Gunn joined the debate to tweet: “Back to the Future SEEMINGLY could be imperfect (why don’t Mom and Dad remember Marty?), but I would still argue it’s a perfect film because there are reasons why this could conceivably be the case (time protects itself from unraveling, etc). Or maybe I’m in denial. Who knows.”
