SAG-AFTRA has filed a labor complaint against Fortnite;s maker over AI use of James Earl Jones' voice as Darth Vader, raising concerns over performer rights.

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 claims that Llama Productions failed to notify the labor group and negotiate when it began employing a James Earl Jones voice that replaced the work of members.
