Big Thinkers is a former ZDTV (later TechTV) television program. It featured a half-hour interview with a "big thinker" in science, technology, and other fields. Interviews were filmed in a 16:9 format and intercut with public domain material from the Prelinger Archives. This archival footage (mostly film clips from the 1940's and 50's) was used to create visual metaphors highlighting the speaker's points.
This episode features Douglas Adams. He was an English author, dramatist, and musician. He is best known as the author of the Hitchhiker's Guide to the Galaxy series. Hitchhiker's began on radio, and developed into a "trilogy" of five books (which sold more than fifteen million copies during his lifetime) as well as a television series, a comic book series, a radio play, a computer game, and a feature film that was completed after Adams' death. Toward the end of his life he was a sought-after lecturer on topics including technology and the environment.
