How to Line a Film Script
This is something I learnt in my days of Script Supervision – how to line a film script. It is a technique to show visually what coverage has been shot for each scene. One day you may find yourself on a film set and see someone drawing wiggly lines on a script, no need to be confused it’s a very simple system that has been used in filmmaking since screenwriting began.

Why should I know how to line a film script?
Because it is easy! If you’re a Screenwriter, Script Supervisor, Director, Editor or Producer you should know this. Some directors like to line their script during filming so that they know what shots they have filmed in each scene (Ridley Scott does). You don’t need to use it as a director but some directors do like to line their scripts up during filming.
So what do these lines on film scripts mean?
A Straight Perpendicular line on a film script means that coverage for the action it crosses has been shot. That could mean either action or dialogue has been captured on screen. The line begins at the start of a shot and the line ends when the shot ends. In the script example below we see a conversation between Matt and John.
At the top of each line the slate number and the amount of takes are written down. The first line above is slate 23, there were 5 takes for this slate. It is a Close Up of John so the line goes straight through John’s dialogue.
What is the significance of a wiggly line?
Wiggly lines on film scripts indicate action that has been recorded off camera. So in the example above the first line has a wiggly line on Matt’s dialogue because it is a close up of John and only he appeared on camera. The second line is Matt’s close up and so there is a wiggly line through John’s dialogue. These days Lined scripts can also be carried out in digital format. See an example below of a digital lined film script. In this example the green lines are being used to indicate sound files to the editor. The sound files 080 and 009 are wildtracks of the location.
