Sony has released on official trailer for the theatrical re-release of Close Encounters of the Third Kind. It will be in theaters on September 1, 2017 in honor of its 40th anniversary, which is November 16th. Sony had previously released a trailer on UFO Day, only saying: "This means something. This is important." They also included the website WeAreStillNotAlone.com, which you can visit and sign up to receive future news regarding UFO sightings. The website's title is a reference to a line from the film that comes from Roy Neary, played by Richard Dreyfuss. Check out the trailer below.
