Just so that other readers are clear about your CU usage, I want to explain for them…

CU [close up] would only be in the script for a few reasons:

1) You are the director and therefore this is your shooting script.
2) It is a shooting script prepared for film production.
3) It is absolutely crucial to understanding the story.

When writing scripts FOR SALE, we must limit directorial type instructions in the script, only adding those absolutely necessary to the story. You want your reader (agents, producers, actors, directors…) to be absorbed in the story, not distracted by the technicalities, most of which will be obvious to them.

Extensive details on how to shoot, how to deliver lines, how to dress, how to set the scene, should be left up to the people who do those jobs, respectively the director, the actor, the costumer, and the set production, and so on. You want to write your screenplay as tight and vibrant as possible.

In Sizzling Popcorn’s example, we will assume that he is the director because that’s how we roll ’round here — a do-it-yourself kind of gang. ;-)
