James Franco is set to play a scientist working on a cure for Alzheimer's by testing on apes. When test subject Caesar suddenly begins to mutate rapidly, the scientist takes him home to remove him from the cruel lab doctors.  Freida Pinto and John Lithgow joined the cast on June 22, 2010. Andy Serkis will play Caesar, the ape that leads the revolt .(ANDY SERKIS ALSO FROM LOTRS)
Tom Felton will also star as the human character Dodge.

Also, I now have some actors to work with in my head, although I think it would make most impact maybe If I just used basically ape type pictures? a giant animal has more effect (at least on me personally) than a human.

+ It was mainly animals used in the original promotions.
