The movie has several vexillologically important flags. When Fossey, played by Sigourney Weaver, arrives in Greater Congo, DR a unique flag representing this nation can be seen at the airport. It is composed of a central white star on a background of green and black divided vertically in the middle, with the fly being black and the hoist being green. The flag also appears on the right side of a jeep.The best shot of this fictional Democratic Republic of Congo flag also appears during the break out of civil war at the Bugani border.
The subject matter of this movie makes it a great case study for any environmental studies class.
Note that Greater Congo, DR did not use such a flag in its history. Perhaps the makers of the film chose a unique design for artistic and politically correct purposes?
