In my classes on storytelling I often talk about spring-loading scenes with seemingly contradictory cues to increase interest through tension.
This does not only encourage the viewer or reader to pay closer attention to the words and actions of the characters, it alerts her to what might be going on under the surface.
Additionally, when the release does finally come, usually at the end of the scene, it has been properly foreshadowed.
Here’s an example:
Imagine an army media-relations Major trying to get out of a dangerous assignment at the war front by threatening to badmouth a General to the media about military losses under his command.
The bad way to write this scene it is to have an exchange of raised voices and angry gestures with one party winning the argument at the end.
The better way is how the screenwriters handled it in Edge of Tomorrow.
In the scene, Major Cage does indeed threaten to ruin General Brigham, but he does this in a calm, almost polite way. Brigham’s response is equally calm and collected.
In the beginning, Cage seemingly holds the advantage. Brigham is sitting down while Cage stands, holding the higher ground, always an advantage in scenes of conflict. He seems to be swaying Brigham with his reasoning.
But the advantage surreptitiously swings over to Brigham when he stands up, towering over the more diminutive Cage, and paces calmly towards him, causing Cage to back up.
Although Cage remains under the impression that Brigham is going along with his suggestion, he betrays his nervousness when he backs up against a chair and is startled.
This small incident reveals the inherent tension in the scene and precedes Brigham issuing orders to have Cage stripped of his rank and dumped at the training camp prior to dropping him into the war zone.
No arm-waving. No raised voices. Just well-written action that moves in counterpoint to the threatening import of the dialogue.
Add tension and interest to your scenes by having the action play out in counterpoint to a threat being delivered through dialogue.
