Please help me to find the movie based on the description of the opening scene.
movie opens along with credits, with a very calm, small stream of water flowing through a jungle. water is flowing very quietly. then some blood is shown in water, followed by lots of dead bodies of soldiers. the stream is very calm and the scene is very quiet, we get an impression that somewhere along the river on high grounds, battle is taking place and the water carried dead bodies downstream.
the uniforms worn by soldiers are definitely modern, by which I mean that they are from an era after ww2.
I saw this opening scene most probably around 2004-2010 in HBO.
