Sohan Roy is coming up with his movie Dam 999 based on dam disaster. The story revolves around a hundred year old dam and populace living around it. The movie raises the environmental issues that are caused by the construction of dam and how it affects the inhabitants in that area. The movie readied to release in December will plea to protest against the dams that are constructed for self interest. The movie is a tribute to those who live under the terror of dam collapse.

Oscar winning film maker James Cameron has also announced that he is planning to shoot a 3D movie on dam, which will highlight the difficulties of indigenous people of Brazil, who are facing displacement over the construction of a dam on the Amazon river. Cameron, who focused on fictitious Pandora land and its inhabitants Na'vi people in blockbuster Avatar, wants to show his support to the local tribes.
