An iconic actor is trying to protect one of his most famous lines from illegal use.

Matthew McConaughey is trying to ensure that it’s not “all right, all right, all right” for unauthorized use of his image or voice by artificial intelligence.

“My team and I want to know that when my voice or likeness is ever used, it’s because I approved and signed off on it,” the Dallas Buyers Club star said in a statement to WSJ on Jan.13.
