Many films product are labelled as controversy, but the author took the parameter by identifying in detail the history of Pacific War through film “Pearl Harbor” and “Tora! Tora! Tora!” by comparison. The research analyses the creation of public opinion of Indonesian society regarding the comprehension of the Pacific War between Japan and the United States of America, after watching and comparing both movies. The spread of public opinion in film is sometimes not realized as the effect of a power instrument by soft-diplomacy.
