Reported i09.com, "While out and about in San Francisco, a commenter named Nolan snapped a few pictures of the infamous ape Caesar. Or at least the stunt mo-cap actor who was filming for this character. According to the onlooker the actor was booking it up and down the hill doing his best 'ape walk.' If you followed any of the past Apes mythology, you know that Caesar is the ape that eventually leads the primate rebellion. So at least we know that in this film he seemingly starts on all fours. Can't wait to see what the special effects team does with this footage."
Caesar: Rise of the Apes, which will reach theatres on June 24, 2011, stars James Franco as a scientist whose experiments to cure Alzheimer's Disease results in the genetic manipulation of an ape named Caesar (Andy Serkis), which ultimately leads to the downfall of humanity.
