Steven Spielberg - Close Encounters of the Third Kind

In the midst of a series of unexplained events, electrical lineman Roy Neary encounters a UFO on a deserted road whilst investigating a large-scale power outage. Roy becomes increasingly obsessed with UFOs and subliminal messaging following his experience, distancing himself from his wife and children but drawing him closer towards parallel investigations being conducted by scientists, the military and other survivors of encounters who are attempting to communicate with the mysterious otherworldly presence.

I had a real, deep-rooted belief that we had been visited in this century. I was a real UFO devotee in the 1970s, and really into the UFO phenomenon from reading. For me, it was science. [...] Police officers make very credible witnesses. At one point, I thought the main character should even be a military person, but you don’t identify with people in uniform. I tried to make this person as common as possible. I wanted to make it about me, my parents, and friends I knew.
