When a synthetic performance resembles a real person, the interesting question is not only how convincing the software looks. Who authorized the use? What exactly was authorized? And which agreement or legal framework is being discussed? Two historical source documents help separate those questions without pretending that one rule settles every use of a voice or face.

Start with the use, not the buzzword
A replacement performance in a film, an altered line of dialogue and a fake product endorsement are different scenarios. Calling all three AI can hide the decision that matters. Describe the output, the person represented, the intended audience and whether the person actually performed what the audience hears or sees.
That is a reporting worksheet, not a legal test. It helps you notice when a headline jumps from a technical capability to a claim about permission. A demonstration that a voice can be imitated supplies no evidence that its owner agreed to an advertisement.
What the 2023 performer document covers
SAG-AFTRA’s explanation of its 2023 TV/Theatrical contracts describes protections around digital replicas, informed consent and compensation. It distinguishes employment-based replicas from independently created replicas and describes specific-use consent rather than a blanket permission for every future production. It also includes exceptions and different rules for different circumstances.
Read the union document as an explanation of that agreement. It is not a license for the whole internet, and it is not proof that a particular producer complied. To evaluate a production claim, a reporter would need the applicable agreement and the facts of the use. This article does not assess an individual performer’s contract.

What the Copyright Office proposed in 2024
On July 31, 2024, the U.S. Copyright Office released the first part of its AI report, focused on digital replicas. It identified gaps in protection and recommended federal legislation addressing knowing distribution of unauthorized digital replicas. The announcement describes a proposal to Congress, not a newly enacted statute.
That distinction is the point of this historical comparison. A recommendation, a negotiated labor agreement and an enacted law are separate kinds of authority. This guide makes no claim about the later passage or current status of any particular bill. Current legal advice requires checking the relevant jurisdiction and subsequent developments.

Consent needs an object
Consider a fictional performer who approves a digital double for one scene. A second use in an unrelated advertisement raises a new reporting question: did the permission extend to that use? The existence of an earlier scan does not answer it. Nor does a statement that the technology is standard practice.
A useful story would identify the project, the permitted use and the source describing that permission. If those terms are private, say that the public evidence does not resolve the question. Do not fill the gap by guessing what a celebrity would probably have accepted.
Read technology claims on three separate tracks
Keep capability, authorization and accountability in separate columns. Capability asks what the system produced. Authorization asks what permission or rule is asserted. Accountability asks who explains, disputes or can document the use. An impressive demo belongs in the first column; it cannot silently fill the other two.
For readers, this approach leaves a more useful takeaway than either panic or reassurance. Ask which problem a source actually addresses, retain its date, and avoid treating a historic agreement as a universal guarantee. This is editorial guidance for reading coverage, not legal advice.
