Unacknowledged, a 2017 feature-length documentary by American filmmaker Michael Mazzola who specialises in exposing secrets, looking at historic files of the Disclosure Project and how UFO secrecy has been ruthlessly enforced and why.
The film, which features narration from actor Giancarlo Esposito (Breaking Bad) presents a collection of declassified information surmounting to our best evidence for extraterrestrial contact.
Yes mainstream media often ridicules or cynically reports on sightings of UFO's but to those who have seen them with their own eyes, it is obvious other beings have visited Earth.
Whether or not you believe UFOs are often visitations by more advanced beings and not just natural phenomena "Unacknowledged" provides a platform for thinking upon. Not only that but the politics behind UFO coverups and why the US keeps reportings of sighting classified while some countries make the information they have public and actually have dedicated departments investigating UFOs.
