Hollywood’s actors’ union filed an unfair labor practice charge against Llama Productions on Monday, alleging the company replaced actors’ work by using artificial intelligence to generate Darth Vader’s voice in Fortnite without notice.

The union has now filed an unfair labor practice charge (link to the PDF is on the SAG-AFTRA website) that calls out “ Fortnite ‘s signatory company, Llama Productions” for “ [replacing] the work of human performers with AI technology” without “providing any notice of their intent to do this and without bargaining with us over appropriate terms.”

SAG-AFTRA, the labor union representing performers in film, television and interactive media, has submitted an Unfair Labor Practice (ULP) filing against Epic Games for using an AI-generated version of Darth Vader's voice in the current season of Fortnite.
