I found that I had forgotten all but a very few scenes since last I saw the movie years back. It is well worth another look for others in the same boat and, certainly for those who have never seen it. It is not, of course, a perfect film, earlier scenes are somewhat too broad in portrayal of the impact on Dreyfuss' imagination as to what such a 'close encounter' might actually entail. Richard Dreyfuss gets solo billing in the brief introductory credits at the beginning of the movie: quite an actor's coup but recognition of the weight put on his performance in sustaining most of the film. Two important female roles are well played  as are a number of other key ones. All in all, still watchable after all these years
