- In physics, the n-body problem is the problem of predicting the individual motions of a group of celestial objects interacting with each other gravitationally. Solving this problem has been motivated by the desire to understand the motions of the Sun, Moon, planets, and visible stars. In the 20th century, understanding the dynamics of globular cluster star systems became an important n-body problem. The n-body problem in general relativity is considerably more difficult to solve due to additional factors like time and space distortions.

What do you do when you’ve got two actors, a bunch of dialogue, and only enough time to get one camera angle? Consider one of the oldest tools in the filmmaking toolbox: the sustained two-shot.
