During the making of Close Encounters Of The Third Kind Steven Spielberg was already kind of a big man in Hollywood. But from the other side he was still young. Technically speaking this was his third theatrical film. He did work for television from the late 60s. At that time he already directed a number of feature length TV movies. One of them was the famous Duel. And then he did only 2 theatrical pictures: the 1972's The Sugarland Express and the 1974's Jaws. And now there is this movie.
