Turning vague action lines into counts
Scripts rarely give numbers. "The bar is packed" and "a few regulars nurse beers" both describe background, and neither tells casting what to book. The breakdown's job is to turn them into counts with descriptions:
| Script line | Breakdown entry |
|---|---|
| "The bar is packed." | 30 BG: bar patrons, mixed ages, Friday-night casual |
| "A few regulars nurse beers." | 4 BG: regulars, 50s-60s, work clothes |
| "A BARTENDER slides a glass." | 1 featured BG: bartender (touches prop) |
| "Cops swarm the lot." | 8 BG: uniformed police (wardrobe fitting) |
Descriptions matter because background often arrive in their own clothes. "Work clothes, no logos, no white" lets them pack the right things. Uniforms, period costumes, and anything wet or bloody mean fittings and wardrobe budget, so flag them. See wardrobe.
The bartender is a special case. A background actor who handles a prop or does a specific bit of business may be a featured extra, and if the director hands them a line, they're a principal.
Background across the schedule
Background counts are also a continuity issue. If the bar in scene 23 has the same regulars as scene 41 two story hours later, the same four people need to be booked on both shoot days. Mark "matching" on the breakdown sheet so the extras casting director books the same faces.
On the day, background check in at a holding area, fill out vouchers or the sign-in sheet, go through wardrobe and makeup, and wait for the 2nd AD or a set PA to place them. Large crowd days need extra PAs, more holding space, more restrooms, and more catering, all of which comes back to the count in the breakdown.
Union rules to keep in mind
On SAG-AFTRA signatory productions, background work is covered by the union's background terms, which set pay, meal periods, and covered zones. The number of background actors who must be hired under union terms varies by agreement and area, and the low-budget agreements handle it differently from the main contracts. Check the current SAG-AFTRA background digest or your production's agreement before assuming a number.
Upgrades are the budget risk. A background actor who is directed to speak a line other than group noise is generally upgraded to principal, which also affects Exhibit G and residuals. Keep dialogue out of background mouths unless it's planned and budgeted.
Our extras breakdown guide has a longer worked example, and the casting breakdown template has a section for background counts.
