Since this movie came out, the government confirmed that UFOs are real, that sightings are increasing, and they might be a national security threat. They don't think they're aliens, but probably advanced drones from a foreign power like China. The government name for UFOs changed to UAP and now to UAUP (unidentified aerospace-undersea phenomena), because now they've been sighted going into the ocean. The Department of Defense also just created an All-Domain Anomaly Resolution Office. In keeping with this theme, I would recommend Arrival with Amy Adams and Jeremy Renner. Might as well throw Interstellar and Contact in there too.
