Back to the Future

In this 1980s sci-fi classic, small-town California teen Marty McFly (Michael J. Fox) is thrown back into the '50s when an experiment by his eccentric scientist friend Doc Brown (Christopher Lloyd) goes awry. Traveling through time in a modified DeLorean car, Marty encounters young versions of his parents (Crispin Glover, Lea Thompson), and must make sure that they fall in love or he'll cease to exist. Even more dauntingly, Marty has to return to his own time and save the life of Doc Brown.

E.T. The Extra-Terrestrial

After a gentle alien becomes stranded on Earth, the being is discovered and befriended by a young boy named Elliott (Henry Thomas). Bringing the extraterrestrial into his suburban California house, Elliott introduces E.T., as the alien is dubbed, to his brother and his little sister, Gertie (Drew Barrymore), and the children decide to keep its existence a secret. Soon, however, E.T. falls ill, resulting in government intervention and a dire situation for both Elliott and the alien.
