Introduction
The unsung heroes of screenwriting, action lines bridge the gap between the ideas in our minds and the way they’re realized on screen.
Action lines are a crucial element that can make or break a script, but you’d be surprised how much they can be overlooked. It doesn’t matter if you’re a beginner or seasoned writer, mastering the art of crafting compelling action lines is key to drawing in readers and directors.
In today’s blog we’ll discuss what makes great action lines, with our all-important top tips to help yours leap off the page and onto the screen! Ready? Let’s dive in!
What Are Action Lines?
You may be more familiar with the term ‘scene descriptions’ and this is essentially what action lines are. They are the narrative elements in a screenplay that describe what’s happening on screen.
Unlike dialogue, the words our characters speak, action lines detail the visual and auditory aspects of a scene, including the action, environment, and sometimes even the mood. Action lines must be concise, vivid, and propel the story forward.
It may be more helpful to think of action lines as answers to key questions, for example, “What do we see?”, “What do we hear?”. The answers given provide just enough detail to guide directors, actors and production teams without overloading the page with excess exposition.
Let’s look at some action line examples. Which do you think is the most effective?
Notice that this action line is quite lengthy, with intricate detail. We don’t necessarily need to know the cup shatters into a hundred tiny pieces; the audience won’t be counting!
Secondly, notice the reference to dialogue “while yelling at Mary.” This should be shown within character and dialogue, not in the action lines. A more impactful alternative could be:
The verbs used here give us a clear image of John’s state of mind. The cup still shatters, as in the first example, however we are left with only the key details, allowing us to move through the story. The same emotion and visual impact are there, but the action lines are concise and easy to read.
In short, brevity is king!
Mastering action lines is just one step toward a great script.
Celtx’s screenwriting software ensures your formatting is spot-on, so you can focus on the story.
The Dos and Don’ts of Action Lines
Now it’s time for the top tips you need to create compelling, exciting action lines. Follow these and your screenplay will be flying high!
Do | Be Specific and Visual
Action lines should paint a picture. Make sure to avoid vague scene descriptions and focus on concrete details that can be translated to the screen.
For example, instead of:
Try this:
Yes, the second example is notably longer than the first, however, there’s more focus on the city’s atmosphere and setting the scene ready for the action that’s about to take place. Short, concise sentences are still used, making it simple for directors and actors to digest.
Don’t | Overload with Adjectives and Adverbs
While it can be tempting to embellish your writing, excessive modifiers will do nothing but bog down your script. By choosing strong, specific verbs and nouns, you immediately eliminate the need for additional fluff.
Which example below has the most impact? This:
Or this:
Do | Keep it Short
Aim for action lines that are three lines or fewer. Large blocks of text can intimidate readers and slow down the pacing of your script. A long-winded example could be:
While this would be a fantastic scene opener for a novel or short story, it doesn’t do much for the screenplay forward. If we were to rewrite this to fit a film or TV show, something like this would be ideal:
Notice that we depict a similar atmosphere to the first description, but with more brevity and focus on the visuals our audience are seeing.
Do | Write in Present Tense
Screenplays should always be written in the present tense to reflect the immediacy of what’s happening on screen. We’re always watching what’s happening in real time.
For example:
Don’t | Direct the Camera
Unless you’re the director, avoid writing too many camera instructions like ‘zoom in’ or ‘pan left’. Let the director decide to frame the shot. Avoid action lines like this:
If you are keen to indicate a specific object or angle to focus on, you can draw attention to these within your action lines without the use of specific camera directions. Use of camera directions sparingly can support your director, but don’t overdo it.
An improved version could be as simple as:
Here, we’re still focusing on the shadow, without including camera angles.
Do | Integrate Visual Storytelling
It’s the age-old saying in the screenwriting world: “show, don’t tell”. Instead of stating how a character feels, use visual cues to express their emotions.
For example, instead of:
Let’s take it one step further and show how Mark is feeling through his body language and actions.
Do | Read Aloud for Flow
A good test of your action lines is to read them aloud. This helps identify clunky phrasing and ensures everything flows nicely.

Examples from Iconic Scripts
Now we’ve covered the crucial dos and don’ts for writing action lines, let’s check out the masters at work. Join us as we explore some of the best examples of action lines in some of the most iconic screenplays from recent years!
Inception (2010)
First, we’re introducing the complex inception machine in Christopher Nolan’s blockbuster hit:
Notice that the sentences are short, focusing solely on what Nolan wants the audience to notice and keep their attention on. By using adjectives like “fly”, we get a clear picture of how Arthur is operating the machine.
Nolan also uses CAPITALIZATION to highlight key props and elements of interest, so they jump off the page. This is a great way of drawing a reader’s attention and can be fantastic for other film departments such as props and costume to refer to.
Check out the clip that this script selection links to. We see Arthur open the silver case with everything inside. While his actions are slightly different from the original script, we still see the atmosphere being created, and the urgency through facial expression and tone of voice.
This is a notable example of how action can be translated on screen. Change is always inevitable on a film set due to the wealth of creativity and ideas bouncing around. What’s important for us as screenwriters, is to set the scene and tone, and the rest will follow.
Parasite (2019)
We’re introduced to the Kim family as they prepare pizza boxes in a semi-basement. The silence between them is emphasized as is the tension through concise yet descriptive action lines.
Just like Nolan, writers Bong Joon-ho and Han Jin-won used CAPITALIZATION to emphasize key elements of the scene for the crew and audience to focus on. While the action lines are a little longer, they still capture the vibe of the scene and the Kim family’s circumstances.
Let’s see the scene in action:
Again, just like Inception, there have been a few changes from script to screen, most notably the inclusion of some extra dialogue before the fumigation truck drives past.
If you’d like even more insight into Bong Joon-ho’s vision for the opening scene of Parasite, check out this clip from Vanity Fair!
