Great Scott! The Cast of Back to the Future Reunites Ahead of the Film's 31st Anniversary

Fans attending the Wizard World Comic Con in Philadelphia witnessed something very special on June 4 when the cast of Back to the Future sat down for a fun-filled Q&A. The "Great Scott! Revisiting Back to the Future" discussion brought interesting insights into the iconic 1985 sci-fi comedy courtesy of the film's three leads, Michael J. Fox, Lea Thompson, and Christopher Lloyd. Although they've all gotten a little bit older (except for Lea — what's her secret?!), the cast laughed it up together and looked like old friends. Check out photos of their sweet reunion here, and then find out the one big thing Back to the Future got wrong.
