Felicity star Keri Russell is set to join Andy Serkis, Jason Clarke, Kodi-Smit McPhee and Gary Oldman in Matt Reeves' Dawn of the Planet of the Apes. She has been cast in the lead feamle role, but there's no information on the character she will be playing.
The sequel is set 15 years after the events of Rise of the Planet of the Apes. They also reveal that one part of the story will focus on a "group of human scientists who are struggling to survive alone in San Francisco." The other part of the story will center on "intelligent ape Caesar [who struggles to] maintain dominance over his kingdom."
After Dark Skies Russell really needs a good movie project, I don't know if you saw it or not, but it was embarrassing bad. I'm sure she'll end up being fine in this movie though, she's normally a decent actress.
Fox has set the film for release on May 23rd, 2014. I loved the first movie, and I hope this ends up being a great sequel.
