A Body Scan Can Outlive a Background Actor’s Day Rate

During the 2023 actors’ strike, the industry’s preferred image of artificial intelligence was a synthetic star generated from nowhere. The more useful image was a background actor walking into a scanning trailer between setups.

Alexandria Rubalcaba, who worked as a background actor on Marvel’s WandaVision, told NPR that workers were directed through a trailer where cameras captured their faces and bodies. She said she received her normal pay for the day but little information about what the resulting scans would become. There is no public evidence that Marvel later deployed her replica. That uncertainty is the point.

A scan has no obvious expiration date. The shift does.

The concrete document to keep beside that scanning trailer is SAG-AFTRA’s background actor digital replica rider, particularly its field for describing the intended use. That blank carries more economic weight than the equipment. Fill it narrowly and the scan is a production tool. Fill it with language covering any project, medium, edit or future technology, and the day’s background wage starts buying something closer to a catalog asset.

The clause does the expensive work

A digital replica is a recognizable digital version of a performer’s voice or likeness, created or manipulated with technology so it can appear to perform without the person doing that performance in real time. The definition covers more than a polished full-body double. A face model, body model or synthetic voice can each move labor away from the worker who supplied the source material.

Under SAG-AFTRA’s 2023 television and theatrical agreements, a producer creating an employment-based digital replica must obtain informed consent. Employment-based means the replica was made from the performer’s work or participation on that production, as with a scheduled body scan. The producer must describe the intended use with enough specificity for consent to mean something, and the scan cannot quietly disappear inside boilerplate that treats every possible use as already approved.

For background actors, union guidance says notice generally must arrive at least 48 hours before the replica is created. If the person is hired inside that window, disclosure is due when they are booked. The actor may request a union representative during the creation of the replica.

Those details matter because consent given after wardrobe, transport and hours of waiting is not commercially equal to consent given at booking. A worker already on location has spent time and may reasonably fear losing the shift, even where the formal agreement protects the right to refuse. The deadline moves the decision closer to the moment when refusal remains practical.

Return to the rider. Its intended-use field should identify what the replica will do in the project, rather than merely naming the project and granting every right around it. A crowd extension for a specified sequence is intelligible. Permission for all uses in all media, throughout the universe, in perpetuity tells the worker almost nothing except that the buyer wants maximum optionality.

Studios like optionality because they do not yet need a plan. The worker bears the price of that uncertainty.

One scan can represent several different transactions

Creation and use are separate economic events. This is the cleanest way to understand the union framework.

The actor supplies time and physical data when the replica is created. If scanning happens during an ordinary workday, that time counts as work time under the union agreement. If a background actor reports on a separate day solely for replica creation, SAG-AFTRA’s published guidance provides for compensation at the applicable background actor rate rather than treating the appointment as an unpaid technical errand.

Use comes later. The producer may place the replica into footage, generate another movement or reuse approved material within the consented scope. Union rules link that use to compensation based on the work the background actor otherwise would have performed. The producer does not get to argue that rendering the body costs nothing merely because the scanning shift was paid.

Put the math in variables. Let D equal one applicable background-actor day rate. If the replica substitutes for five days of work, the labor value at stake is 5D, not the single D that may have covered scanning. If a contract instead buys creation and unlimited future use for D, the producer has converted four days of immediate savings, plus every later reuse it can claim, into value taken from the worker.

That is before considering pension and health contributions tied to covered employment. Background actors generally do not receive the residual structure audiences associate with principal performers, so enforceable reuse compensation matters more, not less. There may be no rich mailbox payment waiting to correct a cheap grant.

The intended-use line determines which side gets the upside. Narrow language forces another conversation when the producer discovers another profitable application. Broad language makes discovery free for the producer.

Reuse is where the grant starts compounding

SAG-AFTRA’s framework distinguishes use in the original project from reuse in another project or context. A producer that wants to carry an employment-based replica into a different movie, series or other covered production generally needs fresh consent and bargaining. Compensation follows the new use.

That boundary is crucial. A digital crowd member in one episode is production work. The same body dropped into sequels, promotional material or an unrelated show becomes a library. Libraries earn money by reducing future purchases.

The risk is not limited to a studio generating a complete speaking character from one afternoon’s scan. Smaller edits can displace work too. A stored body can be repositioned, multiplied, aged, placed in different clothing or combined with another performance. A voice model can generate new words without another recording session.

Each operation looks like postproduction from the buyer’s side and like a lost booking from the worker’s.

Union agreements permit ordinary postproduction work and some digital alterations without reopening every shot. Productions have always adjusted images, changed timing and built crowds. The workplace dispute begins where an edit creates a new performance, materially changes what was agreed or substitutes the replica for labor that would otherwise require the person.

Science-fiction language obscures this distinction. The immediate business case is mundane: secure a durable asset during a temporary job, then lower the cost of future production. No sentient machine is required. A permissive rights grant and a well-organized asset server will do.

Voice belongs in the same file

Body scanning receives more attention because the machinery is visible. Voice capture can be less conspicuous. Clean dialogue, exertion sounds and other recordings may supply material from which a system can derive a synthetic voice.

The same contractual questions apply. The description should say what will be generated, where it may appear and whether new words can be created. Consent to record a person for one scene does not naturally communicate consent to make that person’s voice deliver unrelated lines later.

A producer may also build what the union calls an independently created digital replica, meaning a recognizable replica assembled from existing materials rather than made through a scheduled employment scan. The 2023 agreement still requires notice and consent for covered uses, along with bargaining over compensation. That closes an obvious route around the scanning trailer: skip the new scan, scrape together old footage and claim no new transaction occurred.

The practical enforcement problem remains identification. A background actor may not know that a shoulder, walk, face or voice derived from their work appeared in a dense digital crowd. Consent rights have limited cash value when the worker cannot inspect the asset, trace where it traveled or afford a dispute over a few seconds of screen time.

Union protection has a perimeter

The SAG-AFTRA rules cover signatory productions and workers operating under the relevant agreements. They do not make every online release, nonunion commercial, game, independent production or creator job safe by default. A replica clause can still arrive through a release form written to capture every conceivable right before the worker has an agent, lawyer or union representative nearby.

California added a backstop through AB 2602, which took effect in January 2025. The law makes certain digital-replica provisions unenforceable when they replace work the person would otherwise perform, fail to describe the intended uses with reasonable specificity and were agreed without professional representation by counsel or a labor union. It does not set one universal price for a scan or turn vague language into guaranteed wages. It attacks the broadest form of preauthorization.

That helps explain why representation appears in both the labor agreement and the statute. Consent is not a magic word. Its value depends on timing, information and the ability to negotiate. A checkbox shown after call time, attached to a day’s wage and written to survive every future medium may document a signature while settling none of those conditions.

For workers reading a replica rider, the commercially important parts are concrete: the named production, the described scene or function, the permitted alterations, the period of use, any transfer to another entity and the pay triggered by later deployment. This is not a substitute for advice from SAG-AFTRA, an agent or an attorney. It is a way to see where the money sits on the page.

Go back once more to Rubalcaba’s scanning trailer. The cameras were the visible technology, but the durable mechanism was permission: who requested it, what they disclosed, how long it lasted and whether another payment became due when the file moved. The intended-use field is where a one-day call either stays one day or starts following the actor into productions that have not been cast yet.

Questions people ask

Can a background actor refuse a body or voice scan?

On a covered SAG-AFTRA production, informed consent is required, and union guidance sets advance-disclosure rules for background actors. Whether refusing affects a particular booking can depend on when the replica requirement was disclosed and the terms of the job, so the union or a qualified representative is the appropriate source for an individual case.

Does payment for the scanning day cover every later use?

Not under the union framework. Creation and use are treated as separate events, and deployment of a replica can trigger compensation tied to the work it replaces. Reuse in another project generally requires new consent and bargaining rather than relying on the original scanning payment.

Who owns the digital replica after it is created?

A producer may control the replica file as a production asset, but control of the file does not erase contractual limits on use. Consent language determines the approved scope, while union terms can require further permission and compensation when the producer wants a new performance or a different project.

Are nonunion background actors covered by the same protections?

No. The SAG-AFTRA agreement applies to covered work for signatory producers. State law, including California’s AB 2602, may invalidate some vague and unrepresented replica grants, but it does not reproduce every union protection or guarantee a standard reuse payment.
