I remember this from "Bakit Bughaw sa Langit" (I saw it only once, but I can remember it like it was yesterday): Nora having bought Dennis Roldan a soda pop, and Roldan (he's retarded) telling her he didn't like her. She asks why, when she bought him a soda? Roldan takes back what he said.
Before this O'Hara never used close-ups--mostly long shots and medium shots that take in the whole scene. For the first time he focuses on Nora's face, she smiles and she's radiant, and Roldan smiles shyly in response. It's the first time in the film that these two lonely people actually connect.
Very, very simple scene, but it could be one of the most moving in all of Philippine cinema.
