Serkis: Ape Ceaser strayed into my real life
Andy Serkis "slipped" in and out of being a monkey in his real life while filming 'Rise of the Planet of the Apes'.
The British star - who, through the use of motion capture technology, became ape Ceaser in the new action adventure movie - admits he found it difficult to stop pretending to be a chimpanzee once he had stopped filming and one time found himself running in a primate fashion.
