When filming started in early 2014, it was the last months of Sebastián Piñera's presidency, a center-right-wing businessman. He didn't allow filming in La Moneda Palace (the seat of the President of the Republic of Chile and the real place where the events depicted in the films happened). The cast and crew traveled to Venezuela to film in the Chancellery, which resembles La Moneda Palace.
When center-left-wing Dra. Michelle Bachelet assumed the presidency later that year, the cast and crew returned to Chile to film in La Moneda Palace, under authorization of the president herself, which was very moving for director Miguel Littin and the whole cast.
