Desc: The 20th Century: Yesterday's Tomorrows: Directed by Barry Levinson. With Richard Belzer, Octavia Butler, Phyllis Diller, Spalding Gray. This documentary by Barry Levinson and producers Berge and Rabin takes a look at what we, as Americans, thought the future would be, as we traveled through the 20th century. Houses and cars of the future, the promise of technology, and the other hopes and dreams of the early part of the century gave way to the fears and anxieties brought about by the atomic age and the Hollywood disaster films that followed. Soon we wondered if we could control technology, or if it would control us. This film is by turns light-hearted and thoughtful, and rare historical and archival film, produced by government and industry, alternates with on-screen interviews with people as diverse as consumer advocate Ralph Nader, cartoonist Matt Groening, futurist Alvin Toffler, comedienne Phyllis Diller, and actor Martin Mull.
