 == Sleeper (Woody Allen film) == 

 In view of its creator and star, Woody Allen, the movie Sleeper is satire of trends of the 1970s placed in a futuristic setting. I'm giving as an anachronism a reference to a historical event (the abandonment of clerical celibacy by the Roman Catholic Church) in which a character finds a 1990 newspaper that refers to the ""wife of the Pope"" having children. Such would not happen for at least 24 years after the time suggested in the newspaper.   

 Nobody says that this movie is orthodox science fiction (note that tobacco and junk food have been found wholesome and organic foods have been found harmful in an Orwellian world), but a reference to a 1990 event that is shown to be impossible because a prediction of an institutional change that does not happen for a significant time later becomes an anachronism after 1991.
