Aunor continued making critically acclaimed movies like the period drama Tatlong Taong Walang Diyos . She played the role of a school Teacher , named Rosario , who experienced the atrocities of World War II . Her very convincing performance made her win the first ever best actress award from the Manunuri ng Pelikulang Pilipino ( Gawad Urian Award ) and her first Best Actress Award from FAMAS . it was also considered by many as one of the greatest Filipino movies of all time . The double victory is considered by many as the first acting grand slam since there were only two award giving bodies for movies at that time . Before the year ended , Aunor made '' Minsa ' y isang Gamu-gamo '' ( 1976 ) . This is the story of Corazon de la Cruz , a nurse who wanted to go to America to give a better future for her family , but her brother was shot by an American soldier on the eve of her flight to America . Knowing that the administration of President Ferdinand Marcos would not allow the public showing of any films criticizing the American existence in the Philippines , the producers tapped Aunor to star in the film believing that the superstar had connections with the president and his wife , former First Lady , Imelda Marcos . This film was the official entry of Premiere Productions to the 1976 Metro Manila Film Festival
