Felicity joins the Dawn of the Planet of the Apes, but as a human or a primate?

Dawn of the Planet of the Apes has picked up yet another big name (the last big announcement revealed that Gary Oldman would be playing the leader of the human resistance). And now Variety has announced Keri Russell will be joining the cast which already includes Andy Serkis and Jason Clarke. Fingers crossed she plays a monkey. Seriously, that would be awesome.
