Cryptography is featured heavily in the 1998 film “Mercury Rising” with Bruce Willis, Alec Baldwin and Miko Hughes. The 1992 film “Sneakers” touches on crypro techniques, and the 1988 Vietnam war film “Bat 21” shows a crypto style graphical map key used to rescue a general. National Treasure (1 and 2), A Beautiful Mind, Da Vinci Code, Zodiac Killer, U-571, Up Periscope , Wind Talkers, and A Christmas Story all contain ciphers and cryptology. Most of these movies originated as books and every Sunday in the news paper is a crypto puzzle. Contestants on Wheel of fortune all study the letter frequency and memorize words. Same goes with scrabble players.
