BRUSSELS — Luxembourg has decided not to enter a film in the race for the foreign language Oscar.While the small country has produced eligible films in the past year, the national selection committee came to a majority decision than none was good enough for such a high-profile international competition. This is the third successive year that Luxembourg has sat out. Last year there was simply no film to consider. The year before that, its two major productions were both in English and therefore ineligible. Its last contender was Nicolas Steil’s “Refractaire,” a WW2 drama submitted in 2009 for the 2010 Oscars. The Academy of Motion Picture Arts and Sciences will announce the five nominees for best foreign film on Jan. 10. The 85th Academy Awards ceremony takes place Feb. 24.
