"I didn't imagine that 30 years later, there'd be this enthusiasm and excitement about it. This celebration, I didn't see that coming at all. Back to the Future came out, and there was a two-year lapse, and we did II and III together. We were just making another movie and hoping it gets past opening night. But the kids who saw this film, they've grown up and had kids, who have grown up and had kids. It's exponential, it just keeps spreading out more and more. But the film has aged well. I saw it last night. It seems very contemporary."
