The history of the silver screen is rife with visitors from other worlds, or creatures humans meet in our exploration of deep space. Indeed, some of the most iconic characters in movie history don't always hail from humanity's home planet. From friendly extra-terrestrials who just want to befriend a young boy and share his sense of wonder about our world, to terrifying predators who think hunting humans for sport is the way to go; from chest-bursting monsters who the military foolishly imagine they can weaponize to ghostly, inspiring creatures who come to teach us about our best selves, aliens are all over our culture.
While sometimes they are simply there to entertain or to scare, often they are designed as a way for writers to explore issues that are essential to us, and to investigate our own nature. From the Klingons as a way to observe warrior culture and its parallels in the modern world to District 9's refugee aliens struggling to survive in a concentration camp, aliens help us to take a step back and think about who we are, and who we really want to be.
