If you’ve ever opened a movie script or screenplay, you’ve probably noticed short abbreviations like INT. or EXT. at the beginning of scenes. At first glance, they might look confusing but they’re actually one of the most important parts of script formatting.
Understanding what INT means in a script can instantly help you read, write, or analyze screenplays like a professional. You’re an aspiring writer, filmmaker, or just curious about how movies are structured, this guide will break everything down in a clear and practical way.
In this article, you’ll learn what INT means, where it comes from, how it’s used in real scripts, and how it compares to similar terms all explained in a simple, conversational way.
What Does INT Mean in a Script?
In screenwriting, INT. is an abbreviation for Interior, which tells the reader that the scene is happening indoors.
Example:
INT. LIVING ROOM – DAY
This means:
- The scene takes place inside a living room
- It is happening during the day
Why It Matters
INT is part of something called a scene heading (or slugline). It helps:
- Directors visualize the setting
- Production teams plan lighting and equipment
- Actors understand the environment
Without INT or EXT, a script would be confusing and difficult to produce.
Understanding Scene Headings (Sluglines)
A scene heading usually follows a standard format:
INT./EXT. + LOCATION + TIME
Breakdown:
| Element | Meaning |
|---|---|
| INT. | Interior (inside) |
| EXT. | Exterior (outside) |
| LOCATION | Specific place (e.g., kitchen) |
| TIME | Time of day (DAY, NIGHT, etc.) |
Example:
INT. OFFICE – NIGHT
This tells us:
- The scene is indoors
- It’s in an office
- It takes place at night
Origin of “INT” in Scriptwriting
The use of INT comes from early filmmaking and theater practices, where clear directions were essential for staging scenes.
