Diane Kruger and Fatih Akin reunite for the German period drama ‘Rheingold,’ set in the final days of World War II. Kruger plays a farmer’s wife, while the film follows the coming-of-age story of a 12-year-old boy named Nanning. The film is based on the childhood memories of Akin’s co-screenwriter, German author and director Hark Bohm, who initially planned to direct the film before handing it over to Akin. Warner Bros. Germany, Rialto Film, and Akin’s Bombero are producing the film, with Warners set to release it in German cinemas next September.
