First of all, if you haven't seen Dawn of the Planet of the Apes yet you need to go out and see it now. It's hands down one of the best films of the year. Whether you've seen it or not, here's a beautiful series of concept art that was created for the Matt Reeves-directed movie by the Aaron Sims Company.
ASC worked closely with Weta on both films to design all of the main and ancillary ape characters from the ground up. In the Rise of the Planet of the Apes, they sculpted a bust for Caesar to ensure a hyper-realistic feel. In Dawn of the Planet of the Apes, ASC worked on aging the apes and creating the apes’ ceremonial look, which includes face paint and other ornamentation taken from nature.
These illustrations are stunning and cool. These are part of the reason that this film turned out so freakin' well.
