In “Arrival,” the Heptapods bring with them an easy but cryptic message that requires global unity to comprehend. Initially, however, their words seem militant, sparking worry and paranoia amongst Earth’s armed forces. It’s that sense of mistrust and stress and anxiety that’s shared by the 1951 classic, “The Day the Earth Stood Still.” In it, the United States military thinks that they have good reason to be anxious when a flying dish lands in D.C., however one soldier overreacts when Klaatu speaks, shooting on the humanoid alien. Naturally, that action has huge effects.
Klaatu’s protector, Gort, is big, quiet, and strong, deactivating the military with a single sweep of his eye-beam. However this is just the beginning, and the rest of this story is about finding out to have empathy for each other. Klaatu’s mission to advise humankind towards peace is a substantial endeavor– today, it does not feel like we have actually discovered anything from his words. Nevertheless, the movie ends on a confident note, advising us that it’s not too late to attempt. Like “Arrival,” the answer is to put down our weapons and begin seeing each other as people, not enemies. Yeah, we have actually got a long method to go.
