A Jewish filmmaker’s comedy depicting Hitler (Helge Schneider, right, with Ulrich Mühe) as an impotent, bed-wetting drug addict became the most popular film in Germany in its first week in theaters, Agence France-Presse reported, citing CinemaxX, the country’s biggest theater chain. Despite negative reviews, the film, “My Führer — The Truly Truest Truth About Adolf Hitler,” by the Swiss-born, Berlin-based director Dani Levy, finished ahead of the Ben Stiller comedy “Night at the Museum,” the Denzel Washington thriller “Déjà Vu” and the latest James Bond adventure, “Casino Royale.” The CinemaxX chain based the rankings on box office returns for 339 screens from Jan. 11 to Jan. 14.
