Past, present and future collided yesterday when Universal Studios Home Entertainment reunited the cast and filmmakers of the Academy Award-winning Back to the Future franchise at the Waldorf Astoria in New York, pegged to the original landmark movie's 25th anniversary, and the series' debut on Blu-ray today. Michael J. Fox, Lea Thompson, Christopher Lloyd, Mary Steenburgen and director Robert Zemeckis, among others, all got together, reliving fond memories and recounting their favorite quotes from the films. Clips of the Q&A are up on YouTube; dig in, and enjoy.
