Manila, Open City is a wrong title for the film about the liberation of Manila during the last remaining days of World War II in 1945. Historically, Manila was declared an "OPEN CITY" by General Douglas MacArthur to avoid further destruction and devastation to the city upon the arrival and invasion of the Japanese imperial forces in the country in 1942 to start World War II.
One of the most vivid and detailed depiction of World War II in a Filipino film.
