Plot SynopsisVery Early Tuesday Morning, September 13, 1966: 12:35 amThe opening title credits played above a nighttime scene - the arrival of a Gulf, Mobile & Ohio passenger train into a small town""s station (the town was identified by a welcome sign as Sparta, Mississippi), accompanied by Ray Charles"" rendition of the title song:In the heat of the night, seems like a cold sweat creepin"" cross my brow, yeah.First Fred Astaire, then Ginger Rogers.After they swirl toward the camera, the picture then dissolves to a shot of a black top hat, over which the remaining credits are superimposed.It was also a milestone in liberalized attitudes toward film nudity and expressions of sexuality (reportedly the first British film to display full-frontal nudity), and forced changes upon the current MPAA rating system.Like the man-apes before him, Dr.Floyd is similarly awed and stirred by his first view of the alien form - it is a religious experience as the men worshipfully gaze at the altar where the monolith stands.
