Here’s how fast motion-capture technology is evolving: On Rise of the Planet of the Apes, all the motion-capture work had to be completed after principal photography had been completed, but on Dawn of the Planet of the Apes, just a few years later, the ape actors shot alongside the human actors on set, even in exterior locations. That’s just one of the facts packed into the latest episode of You Think You Know Movies, which gets into some serious monkey business with Dawn of the Planet of the Apes!

Director Matt Reeves wanted to make a fix to the ending of Dawn of the Planet of the Apes, but the actors were unable to get together for reshoots. So, Reeves got on Skype with Andy Serkis, who was in London, and Jason Clarke, who was in Los Angeles, and directed each of them from 6,000 miles away, over the computer. That’s a technological achievement almost as impressive as all the motion-capture work.
