One of the most iconic parts of Back to the Future is the time traveling DeLorean. But, in earlier versions of the story, the DeLorean was nowhere to be found. Originally, Marty McFly was going to back to the 1950s in a refrigerator! And, instead of being powered by plutonium, it was powered by a nuclear explosion and Coca-Cola. Get ready for even more facts from the future in the latest installment of You Think You Know Movies!

In one of the funniest parts of the movie, Marty tries to prove to Doc Brown that he's from the future by naming the current U.S. President. “Ronald Reagan? The actor?!” That line had to be approved by the White House and Steven Spielberg screened the film for Reagan, the former actor. Reagan liked the movie so much he not only approved the line, but actually quoted the film in one of his State of the Union addresses.
