A vibrant celebration of Roma culture set against the backdrop of World War II-era France, “Freedom” follows a close-knit band of Roma gypsies on their annual trek to a Vichy village to help with a wine harvest. The town’s mayor goes to great lengths to protect them from being harassed by the occupying Nazi forces, but it’s only a matter of time before the Nazis mount a campaign to round up the Roma and send them to an internment camp. Director Tony Gatlif (“Indignados”), who has proven himself a masterful chronicler of the Roma experience in past films like “Latcho Drom” and “Exile,” offers a graceful, poetic tribute to the hundreds of thousands of Roma who are often overlooked as victims of the Holocaust. In French, German and Romany with English subtitles.
