Corrected entry: When Zira is being interrogated, she says that the planet was destroyed in 3950 or something. The interrogator, later tells the President that the Earth was destroyed in 3955. In the original Planet Of The Apes, the ships display at the beginning of the movie shows that Taylor and his men crash landed in the year 3978. This would have been over 20 years later. Yet the planet was blown up in Beneath The Planet of the Apes at the end of the movie. So the timeline is impossible. (00:43:25)
Corrected entry: After Dr. Hasslein shoots the baby chimp, Zira pushes the baby over the side of the ship. The baby chimp lands in the water and floats. It floats as if it were made of plastic and weighed nothing. Had it been a real chimpanzee baby it would have had some weight to it and gone under water.luchador
Corrected entry: In the scene when Cornelius and Zira are being interrogated, Cornelius talks about how the sacred scrolls tell of the first ape that talked. Yet in the first film, they denied this, saying apes came first and that's why they had to destroy the doll in the first film. So either Cornelius or Dr. Zeus is wrong about what's in the sacred scrolls.
Corrected entry: Throughout the POTA movies, chimpanzees are portrayed as peaceful pacifists, while gorillas are prone to violence. Later scientific discoveries prove (at least in some respects) the reverse: while gorillas are the more peaceful apes, getting violent only to protect their families or territory, chimpanzees have been found out to eat meat as well, attacking and dismembering small animals and even monkeys.
