Query: When did Spectre begin production in Austria?
Context: Filming started in Austria in December 2014, with production taking in the area around Sölden—including the Ötztal Glacier Road, Rettenbach glacier and the adjacent ski resort and cable car station—and Obertilliach and Lake Altaussee, before concluding in February 2015. Scenes filmed in Austria centred on the Ice Q Restaurant, standing in for the fictional Hoffler Klinik, a private medical clinic in the Austrian Alps.
