The Abandoned Field: Free Fire Zone (Vietnamese: Cánh đồng hoang) is a 1979 Vietnamese drama film directed by Nguyễn Hồng Sến. It won the Golden Prize and the Prix FIPRESCI at the 12th Moscow International Film Festival.
The film gives an "unnerving and compelling .. subjective-camera-eye-view" of life under helicopter fire in the Mekong Delta during the Vietnam War. The film cuts to an (American) "helicopter-eye view", contrasting painfully with the human tenderness seen earlier.Synopsis
The film completely takes place within the perimeter of an empty field, but it exploits both the space under the water (from under the water surface of the field) and the edges of the sky (where there are American warplanes conducting raids).
