The credits list is the most valid of the sources. Shambala is right on this. If he is written on the credits list, then he should stay on the cast list of the page, if not, then if he appears he is going on uncredited cast, but if he is mentioned only (not appearing on credits either) then he doesn't belong on the cast list, but a page would still be created as he would be a character in the universe.
