"They paved paradise to put up a parking lot"

As two of my most revered and revisited films, the inclusions of both Chinatown and Wild River, each of which I consider to be among the finest their respective decades offer, prompts comparisons of the two, and the ways in which common dramatic catalysts - water, its control and distribution through massive, publicly-funded projects and the displacement of those such efforts bring about - result in entirely different films despite numerous similarities.

Not intending to subvert the thread topic, it always seems to me the solicitation of titles sharing a common theme provides opportunities to look at any of them in greater depth, and to explore the ways in which they employ that theme.
