Fine print.
Some companies reserve the right to use the image, likeness, whatever, of anyone they AUDITION, and NOT say it belongs to someone, (or something to that effect), even when that person is not hired, as long they don't relate the character directly to someone.
Or any employee, regardless being auditioned or not.
For example, they could copy your face and place over a random NPC in any game if you ever worked for a game company.
It would usually be in Fine Print, in a loooong contract. You could have one of those for yourself, RIGHT NOW, and not be aware of it.
Without a contract, it usually doesn't work, like Lindsay Lohan tried. Did this guy make a contract protecting his image, before audition or motion capture? Nope?
