In 1950, a Code of Motion Picture Censorship was instilled, further identifying what aspects were considered as censorable. Scenes that depict drunkenness as attractive, scenes that depict drug trafficking, and scenes that deal with sex and surgical subjects "when shown to selected groups" are some examples of scenes that were put under review. Foreign films banned at the time include "The Moon Is Blue" (Dir. Otto Preminger) in 1954, and "Martin Luther" (Dir. Irving Pichel) in 1953. "Perlas ng Silangan" (Dir. Pablo Santiago) was screened without edits, which spiked a protest from the Provincial Board of Sulu, claiming that it misrepresented Muslim culture.
