Casting Notes

The Core Function

A casting note is the writer’s first opportunity to bring a character to life on the page. It’s a short, evocative description included in the action lines the very first time a character appears in the script. Its purpose is to give the reader—and subsequently the producers, director, and casting director—a clear and immediate sense of the character’s age, essence, and defining traits.

Standard Industry Formatting

When a character is introduced, their name is written in ALL CAPS. This is typically followed immediately by their age (or age range) in parentheses, and then a brief description before the action continues.

INT. OFFICE - DAY

The door opens and in walks DETECTIVE MILLER (50s), a man whose rumpled suit and weary eyes suggest he's seen it all twice. 

Across the room, CHLOE (20s), sharp and energetic in a pantsuit, doesn't look up from her laptop.

Best Practices and Common Mistakes

• Focus on Essence, Not Appearance: The most effective character introductions describe personality and soul rather than just a laundry list of physical attributes. Instead of “blue eyes, brown hair,” try something that suggests character: “a smile that doesn’t reach his eyes.”
• Keep it Brief: A single, well-crafted sentence is often more powerful than a full paragraph. The goal is a memorable first impression, not an exhaustive biography.
• Avoid Naming Specific Actors: Stating that a character should be ‘a Tom Cruise type’ can be counterproductive. It dates the script and can needlessly limit the casting director’s imagination.
• Give a Sense of Contradiction: The most interesting characters often have an element of contradiction. For example, “a bodybuilder who moves with the grace of a dancer.”

Why It Matters

A strong character introduction is a crucial piece of storytelling. It immediately anchors the character in the reader’s mind and provides a clear and inspiring springboard for the casting director. It sets the tone for the character’s role in the story and is the first step in attracting the right actor to bring them to life.
