Locations and conflict

One more thought on locations - they can create conflict, or tension. 

Example:

Knife in the Water

As the title suggests, there is tension in this location. Most of the film is shot on a boat which runs through the water. The boat at times becomes a prison. A jail for the three characters. Surrounded by water. Nowhere to go.

As the tension mounts between the two men, the boat and water serve to fuel that tension. There is no where to escape. The boat is a knife in the water.
