The remarkable story of The Weather Underground, radical activists of the 1970s, and of radical politics at its best and most disastrous.

The Universal Language is a new documentary from Academy Award-nominated director Sam Green (The Weather Underground). This 30-minute film traces the history of Esperanto, an artificial language that was created in the late 1800s by a Polish eye doctor who believed that if everyone in the world spoke a common tongue, humanity could overcome racism and war. Fittingly, the word “Esperanto” means “one who hopes.” During the early 20th century, hundreds of thousands of people around the world spoke Esperanto and believed in its ideals. Today, surprisingly, a vibrant Esperanto movement still exists. In this first-ever documentary about Esperanto, Green creates a portrait of the language and those who speak it today that is at once humorous, poignant, stirring, and ultimately hopeful.
