The upcoming late summer film, "Rise of the Planet of the Apes" (POTA) will feature the super-intelligent apes with the use of sign language to communicate with each others.
The rise of apes overtake human beings as the supreme order of life after the genetic
engineering with ape breeding went all wrong.
That must be very interesting to view the "Rise of the Planet of the Apes". The original film series of the "Planet of the Apes" from the 1970s - "Conquest of the Planet of the Apes" did not include any kind of sign language within the chimpanzee known as "Cornelius".
