As an actress, she is regarded as one of the best in the business because of the quality movies, television shows and stage plays that she did.  She was named by NO!

Himala ("Miracle") is a 1982 Filipino drama film directed by Ishmael Bernal and produced by the Experimental Cinema of the Philippines.  The film's script was written by Ricky Lee based on the story of a teenage girl on Cabra Island in the province of Occidental Mindoro between 1966 and 1967. Lamberto Vera Avellana (February 12, 1915 – April 25, 1991) was a prominent Filipino film and stage director.  Despite considerable budgetary limitations that hampered the post-war Filipino film industry, Avellana's films such as "Anak Dalita" and "Badjao" attained international acclaim.  In 1976, Avellana was named by President Ferdinand Marcos as the very first National Artist of the Philippines for Film.  While Avellana remains an important figure in Filipino cinema, his reputation as a film director has since been eclipsed by the next wave of Filipino film directors who emerged in the 1970s, such as Lino Brocka and Ishmael Bernal.

Released at the height of the Marcos regime, the film uncovers the other face of Manila by depicting the ugly aspects of life in the city - unemployment, prostitution, drug addiction, and lack of decent housing.  Considered as one of Bernal's masterpieces, it is an epic multi-narrative of people who have shady pasts and are trying to exist in an unforgiving world.
