After traveling back to 1955 in his friend Doc Brown's (Christopher Lloyd) time-traveling DeLorean, Marty McFly (Michael J. Fox) accidentally prevents his parents (Lea Thompson and Crispin Glover) from meeting. Now, he must make sure that they meet and fall in love at the "Enchantment Under the Sea" high school dance – or he may never exist! The 1985 action-comedy directed by Robert Zemeckis and executive-produced by Steven Spielberg hits all the right notes, right down to the Huey Lewis tune "The Power of Love," and made Fox a bona fide movie star. Of course, two sequels followed, finding our heroes 30 years in the future (2015) and 100 years in the past, in the wild west of 1885. Get the movie.
