The Atomic Cafe is old, but it's something everyone should see.
Here's a blurb from wikipedia:
The film covers the beginnings of the era of nuclear warfare, created from a broad range of archival material from the 1940s, 1950s and early 1960s including newsreel clips, television news footage, U.S. government-produced films (including military training films), advertisements, television and radio programs. News footage reflected the prevailing understanding of the media and public.
--edit
In 2016, the film was selected for preservation in the United States' National Film Registry by the Library of Congress, being deemed "culturally, historically, or aesthetically significant".
