For 11 weeks during the Summer and Fall of 1985,
"Back to the Future" was America's number one film.
"It was just so original. It was nothing we'd ever really seen before", said Tim Stack of �Entertainment Weekly�.
Michael J. Fox played time traveling teen Marty McFly, who encounters his parents as high school students in 1955.
The role turned a TV star into a movie star.
"Going to the movies is like going to church�, says Fox. �And when you make it on the big screen, it really changes things and people hold it in a whole different regard."
In this case, even the White House took notice.
"He laughed so hard, he missed the next 2 minutes of dialogue", recalled writer Bob Gale.
The film made such an impression that President Reagan even borrowed from it.
"I grabbed the phone and said, Bob, did you hear what Reagan said about your movie?�, said Steven Spielberg, the film�s director.
And, 25 years later, fans still want to talk about it.
"People want to talk about the space time continuum and stuff and I'm like dude, I was just in the movie!", joked Fox.
Other "Back to the Future" fans embraced the film on a much more basic level.

"It's a very sweet, nostalgic, lovely movie that I don't know if it would be made today", said Stack.
But making it 25 years ago made it a classic.
