Final answer:
An unbroken span of action in a movie is called a shot, while continuous narrative refers to a storytelling method in the arts where different scenes are connected within a single framework to portray the progression of time.
Step-by-step explanation:
A span of action in a movie that is unbroken is known as a shot. This refers to a single stream of footage without any cuts, from the time the camera starts rolling until it stops. In contrast, a continuous narrative is a method of visual storytelling used within the arts, particularly in graphic novels, where a storyline is depicted across multiple scenes within the same framework, and time progresses as the narrative unfolds.
