The Day After (1983) movie

The chillingly realistic docu-drama The Day After (1983) depicted a nuclear missile exchange between the United States and the Soviet Union in the early 1980s. Some of the most compelling scenes are of the Minuteman missile launches from silos in Kansas. Jason Robards, Jobeth Williams, John Lithgow and Steven Guttenberg were among the stars of this terrifying and haunting film directed by Nicholas Meyer and written by Edward Hume. Unlike the TV series Jericho, no punches were pulled in showing the devastating impact a nuclear attack would cause. At the end of the movie we are cautioned that an actual attack would have caused much more destruction than seen in the movie.

Skeptic magazine (vol. 15, no. 2, 2009) published an article by David Morrison titled "2012 and Counting: A NASA Scientist Answers the Top 20 Questions About 2012." Most of the article is about the bogus (fictional) planet Nibiru, also known as Planet X, around which there is supposed to be a conspiracy to conceal its existence. According to Morrison's introduction, "I answer questions from the public submitted on-line to a NASA website (astrobiology.nasa.gov), and over the past two years the Nibiru-2012 doomsday has become the dominant topic people ask about."

The Wikipedia entry on the Doomsday Clock contains many more fascinating details, including how the clock has been incorporated into popular culture.
