The skilful use of body language to display character intent both in screenplays and novels is a necessary skill, since it forms part of the show-don’t-tell arsenal of techniques that makes writing visual.
Take the following snippet from my novelette, The Nostalgia of Time Travel.
To put you in the picture – Benjamin Vlahos, the protagonist of the story, watches an apparition, a version of himself, slumbering in a deckchair in his candlelit room while a cyclone approaches.
I could have written:
I stare at the slumbering figure intently. He seems pained, buffeted by raging nightmares. I can’t help but wonder about the extent of fear and regret tormenting him.
Pretty lame, right? Instead I wrote:
I study the ashen-faced man slumbering in front of me. His lips tremble. His eyes rage behind closed eyelids. His jaw grinds down on the bones of all the years.
This is better.
“Show don’t tell is one of the most powerful writing techniques in the writer’s toolkit.”
Although the body language centers around small actions, such as trembling lips and a grinding jaw, and throws in a metaphor to boot, it does a better job at conveying the tormented inner life of the sleeping figure. It obeys that much vaunted bit of advice of showing the reader the clues and letting her work out the emotion for herself, rather than handing it to her in a platter.
The use of body language to convey the inner state of a character is a powerful technique that helps to keep an audience or reader engaged in the story. It should always replace a spoon-fed description of a character’s emotions.
Use body language to describe a character’s inner life, and do so through the show don’t tell technique.
