You’ve seen The Battle of Algiers. You’re preparing for the Battle of New York City this summer. So this Sunday, see the We Interrupt This Empire . . . , last year’s battle of San Francisco against the invasion of Iraq. It’s at Anthology Film Archives as part of the New York Underground Film Festival.

Not familiar with the tortured genius Munch? Try the Great Norwegians page.
