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.
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".
