i understand that with saying 5 celebs in CotD, you meant to add on George A.Romero. But i think what he meant is celebs who have actually been hired to voice the characters. And I do not think they actually got King of the zombies George to voice himself in CotD. Same goes with Five. As for MotD, you're quite right. Until you actually mention it, i didn't know that the one voicing Al was Cypher from Matrix!!! So, i guess we can say Treyarch started it all with this celebrity fashion.
