In an interview with Good Housekeeping magazine, the 49-year-old expressed pride that audiences still enjoy the time-travelling adventures of Marty McFly and Doc Brown (Christopher Lloyd) even as the futuristic technology shown in the movies becomes less far-fetched.
"If I'm changing the channel, sometimes I'll see them, and I'll pause for a second," Fox said. "I love that people still see it."
The star went on to say: "It's funny that a film about multigenerational relationships, characters over a span of generations, has become a film that's been popular over a span of generations. In fact, we're almost at the place in the future that Marty went to. Fast approaching, and there are no flying cars."
Fox recently insisted that he tries not to let his battle with Parkinson's disease alter his positive outlook on life.
He will return to television alongside Larry David, Rosie O'Donnell and Ricky Gervais in the eighth season of Curb Your Enthusiasm, which is to premiere on July 10 on HBO.
