CLOSE ENCOUNTERS OF THE THIRD KIND

US, 1977, 152 minutes, Colour.
Richard Dreyfuss, Melinda Dillon, Francois Truffaut, Teri Garr, Bob Balaban.
Directed by Steven Spielberg.

Close encounters of the first kind: sightings at close range, usually within a hundred feet. Close encounters of the second kind: sightings followed by the finding of physical evidence, such as landing marks on the ground, scorched earth or broken vegetation. Close encounters of the third kind: the most dramatic of the sightings when "occupants" of the U.F.O. are seen and, in some cases, physical contact is made with them.
