The genetically enhanced apes from the previous film "Rise of the Planet of the Apes" inherit a post-apocalyptic San Francisco in "Dawn of the Planet of the Apes." And Andy Serkis reprises his role as top-chimp Caesar.

Terry notary teaches the actors how to move like apes. Arm extensions allow them to walk on all fours. After six weeks of training with terry, the actors must learn to sound authentic, too.
