DUCK AND COVER (1952) ¢ ¢ ¢
D: Anthony Rizzo
A generation of Cold-War-era schoolchildren grew up with this educational short in which a cartoon turtle shows kids how to protect themselves in the event of a nuclear attack. As time-capsule artifacts go, the movie's both funny and horrifying. It was added to the National Film Registry in 2004, and turns up as a segment in "The Atomic Cafe" (1982).
