The funny little frog to the right can mean only one thing: The Environmental Film Festival is back. Now in its 19th year, the festival has become a massive understaking, where 150 films from 40 different countries—most for free—-screen at museums, embassies, libraries, universities, and movie theaters throughout the District. This year’s programming is particularly diverse, including countless screeds against our continued mishandling of fossil fuels, the winner of the 2010 Palme d’Or at Cannes, the D.C.-area premeier of gonzo documentarian (and shoe-eating enthusiast) Werner Herzog’s Happy People: A Year in Taiga, and the surprisingly topical The Light Bulb Conspiracy, which hopefully sheds some light (wakka wakka) on 2011’s most bizarre lightening rod issue for grandstanding members of Congress. Keep checking back with Arts Desk throughout the festival for highlights and recommendations.
