In 1964, with the Northern Hemisphere rendered uninhabitable in the wake of nuclear war, an American sub commander (Gregory Peck) sets sail for a still-thriving Australia, in the faint hope of someday hearing an all-clear from the U.S. Meanwhile, a tense Australian populace begins to gird for the inevitability of the fallout drift. Stanley Kramer's somber speculation, adapted from the Nevil Shute novel, co-stars Ava Gardner, Fred Astaire, Anthony Perkins, Donna Anderson. 134 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital stereo; Subtitles: English; theatrical trailer.
