Action in a story always serves a purpose when done well. To make sure action scenes are effective, consider what they ask of the reader and how they advance the plot.
The Nature of Action Scenes
When it comes to the nature of action scenes, it is important to recognize that a big difference between movie action scenes and written action scenes is what they ask of the reader.
Action scenes in movies require no audience participation, but in written form they require a lot of reader participation, particularly with fight scenes. It takes effort to understand what is happening in a fast-paced action scene. Action, in general, is often chaotic. To readers, action scenes can easily become confusing for the reader to follow what’s going on if it is not written clearly and interwoven with other components. Action works best when balanced with description, exposition, internal dialogue, and emotional reflection.
Why something is happening is just as important, or more important in some cases, than what is happening in the scene. Makes sure the why is clear during an action scene in order to prevent the reader from getting bored or lost in an endless description of movements.
Asses an action scene to make sure what you are asking of the reader provides an equal payoff, by having a purpose that is understandable and clear.
Using Action to Advance the Plot
Action must matter to the story itself, or it won’t matter to the reader. When considering what is the point of an action scene, ask what you are hoping to accomplish with the action scene.
Purposes behind action scenes might include revealing information, providing character development, affecting the rest of the story in some way, making the reader ask important questions, showing or revealing a character’s skill or talent, providing a transition, etc. Once you pin down the purpose of the scene in relation to the overall story, make sure that is also apparent to the reader.
If you cannot define the purpose, or the scene seems to be accomplishing nothing, cut it or rework it to fulfill a clear purpose. Then evaluate the scene again. Does the action scene actually accomplish its purpose? Critically assess it to make sure the scene adequately addresses the purpose in a clear way. Beta readers can be a wonderful resource in assessing single chapters to determine its purpose. A reader should finish the scene having learned something important about the character or story.
