If only we were there!  It was an epic reunion. Michael J. Fox and Christopher Lloyd delighted “Back to the Future” fans when they were reunited over the weekend, 37 years after the release of the sci-fi comedy.   The pair, who respectively starred as time-traveling high school student Marty McFly and eccentric “Doc” Emmett Brown in the 1985 blockbuster and its two sequels, appeared together at New York Comic Con on Saturday to speak on a panel about the modern classic’s legacy.   Lloyd, 83, made sure to document the moving moment by sharing a picture of the pair embracing on stage at Comic Con on his Instagram Stories. The caption read: “Thank you @newyorkcomiccon you were wonderful.”
