BERLIN — Volker Schloendorff’s World War II drama “Calm at Sea” and Tony Gatlif’s “Indignados,” about the protest movement that spread across Europe last year, are among the films unspooling in the Berlin Film Festival’s Panorama sidebar this year.

“Calm at Sea” is a fact-based drama about the German occupation of France, including the story of Guy Moquet, the young French communist hero executed by the Nazis who remains a symbol of the French Resistance, as well as those of acclaimed German writers Ernst Juenger and Heinrich Boell, both of whom served in France with the German army.

Highlighting a different type of occupation, “Indignados” examines a Europe in revolt through the eyes of an illegal female immigrant, who experiences the Occupy movement and the dissatisfaction of a young generation of European society. The pic will open Panorama Special.

Fest organizers on Tuesday unveiled the first 20 films that will screen as part of the Panorama sidebar, which also includes the Main Program and Dokumente sections in addition to Special. The complete lineup will include some 50 titles.

Also opening Special is Polish director Malgoska Szumowska’s drama “Elles,” starring Juliette Binoche.

Ira Sachs’ U.S. gay drama “Keep the Lights On,” starring Thure Lindhardt (“Flame and Citron”) and Zachary Booth; and Sheldon Larry’s U.S.-Canadian feature “Leave it on the Floor” also unspool.
