Casting Breakdown

A casting breakdown is the per-role description released when a production begins casting: character name, age range, essential traits, the role's function, and any hard requirements (skills, languages, union status), plus role size — lead, supporting, day player, under-five.

The breakdown is a compression algorithm run on your script. A casting director reads the screenplay and reduces each character to a paragraph that agents can match clients against. Writers should understand this because your character either survives that compression or doesn't. "SARAH, 30s, a fixer who's tired of what fixing costs" is castable — an agent instantly thinks of clients. A character described only by plot function ("MIKE, Sarah's contact") gives casting nothing to want, which is a sign the role is thin on the page.

The professional artifact is also a legal one: breakdowns state union terms and pay, and casting platforms police accuracy. Vague breakdowns ("great exposure, deferred pay") signal amateur productions to every rep who reads them — the fastest way to cast badly.

The writer's move: before submitting, write the breakdown paragraph for each of your top five roles. If one is hard to write, the character needs work — which is exactly what the character dimension of our scorecard measures. Productions post breakdowns on our casting board.
