Well typically the likenesses of characters are based on someone so it might as well be a famous person instead of a face model or what have you. Uncanny valley will always exist, doesn't matter how good something looks. I do think Ellie from the Last of Us looks more like Ellen Page than Jodie does.
I don't mind. It's a little distracting in a way now, but as it becomes more common it won't be. I thought LA Noire did the digital acting very well with less of "stars" in the roles and GTA V did with much less known actors.
It'll just be something that happens as digital acting becomes bigger and it's a good sign.
@fredchuckdave: Well, the difference to me is that if that digital actor is not well known/famous I wouldn't/couldn't know them, so for me there would be no difference to a completely made-up character - so my immersion stays intact. Dafoe on the other hand is Dafoe first, and his in-game character second.
I can accept them swatting at the uncanny valley thing for another 10 years and I am in no way against digital acting or mocap or whatever, just that "here is your favorite movie star as an incentive to buy this game" approach.. somehow that leaves a bad taste in my mouth. PR grabbing by latching onto stardom, sales projections "With E. Page vs. without E. Page" and such..
If you say "yes, because then it's like movies", it somewhat implies games are striving to be like movies, which isn't true, nor should it be. Movies are one thing, games are another. However, I do like it because, just like in movies, it lends a familiarity to the characters. Much like in movies, even though they're playing different characters/roles, you still know the actor and thus feel... something when watching different movies.
The question now is, should games borrow movie actors, or should they establish their own roster of actors exclusively for games or even to cross-pollinate both rosters/mediums. As a fan of cross-media "initiatives" or whatever the fuck the marketing buzzword is for using different mediums to portray a character (movies, games, books, etc) I approve.
