They kind of look the same, IMO.
What would I care if someone used my likeness?
Actors take that very seriously. In Back to the Future 2, when Marty's parents came over to hydrate a pizza, George enters the house upside down because his back was thrown out. Well, that was not the same actor (Crispin Glover) as the first film. Crispin sued because they used his likeness. He won the lawsuit.
