Clearly, Steven Spielberg has a thing for space and aliens. E.T.: The Extra-Terrestrial follows the story of Elliot (Henry Thomas), a young boy who takes in a stranded alien who is accidentally left behind on Earth. Elliot, along with his brother and sister (a young Drew Barrymore), helps E.T. get home while also keeping him a secret from their mom and the government. Completely cinematic and heartwarming, I dare you not to cry while watching this movie.
