Development In 1977, LVN Pictures celebrated the centennial of its founder, Narcisa de Leon, who was also the grandmother of director Mike de Leon. Although the company had not produced films for several years, de Leon's father, producer Manuel de Leon, approved producing one film in celebration. Director de Leon and his co-screenwriter Rey Santayana conceived of the film ''Kung Mangarap Ka't Magising'' as a tribute to the romantic musicals of LVN Pictures. The story was inspired by the 1966 French film
A Man and a Woman directed by
Claude Lelouch. The initial storyline, however, was criticized as "too much like a European film" by producer Manuel de Leon. The director subsequently added a traumatic past to the main character. Nevertheless, there is still a touch of what film academic Patrick Campos describes as "the sensibility of the European art film." Neither director-screenwriter de Leon nor his co-screenwriter Santayana had previous screenwriting experience, and so some scenes were made up as filming went on.
Filming and post-production The film was shot in
Baguio and
Sagada. As shooting went on, de Leon and Santayana discussed whether scenes should be shot in Manila as well, but the co-writers ultimately decided to keep the entire film in the
Cordillera. An exception, however, was a flashback scene of a cocktail party set in Manila, which was filmed at the home of Narcisa de Leon. The home had been used as a shooting location for older LVN films, including its first film
Giliw Ko, and would be used again in director de Leon's follow-up film,
Kakabakaba Ka Ba?. In the initial script, the character of Ana's son had a larger role, but de Leon found the child actor playing the son difficult to work with and subsequently wrote most of his scenes out of the film. Christopher de Leon learned how to play the piano for the role of Joey. Hilda Koronel recalled that the young actors on set, including actor de Leon and herself, would go out at night, but still make the early call times, even if just with an hour of sleep. The film was dubbed in post-production.
Music The film was scored by Jun Latonio, in his first film work, with the assistance of lyricist Joseph Olfindo. They were both students at the
University of the Philippines College of Music whom de Leon met through his cousin, Nonong Buencamino. Olfindo would later suggest the music-related "wild concept" that would develop into de Leon's next film,
Kakabakaba Ka Ba?. Latonio would go on to score other films including
Joey Gosiengfiao's
Temptation Island and
Laurice Guillen's directorial debut
Kasal?. == Release ==
