Last night "The People Speak" previewed at Lincoln Center's Rose Theater.

Project participants Matt Damon, Viggo Mortensen and Josh Brolin attended the screening, as did Emily Blunt, John Krasinski, Lola Schnabel, Lupe Fiasco and Wallace Shawn.

Airing on the History channel, the show is a collection of letters, diaries and speeches stressing the need for social change. Narrated by author Howard Zinn, the work is based on his books "A People's History of the United States" and "Voices of a People's History."
