Corrected entry: When the astronauts first found life, the flower, there are 3 backpacks. Subsequent scenes while walking through the desert show the 3 men with the 3 packs. However, in the scene where the astronauts are going through the canyon, and are being observed from above, the first astronaut, Dodge no longer has his pack which contained food and water.
Corrected entry: The wound on Charlton Heston's neck is never more than a little bit of red paint smeared on his skin. The plot suggests he was shot in the neck with a gun, explaining why he cannot speak to defend himself (though it was unrealistic, since he couldn't even utter any sounds). Understandably, this movie was made in 1968, so special effects and makeup were limited, though you would expect them to put more effort into the illusion of a gunshot, especially for something so critical to the plot.
Corrected entry: If any disaster were to occur such as what happened here, the Statue of Liberty would be the first thing to go. Yes, it stood up in Day After Tomorrow, but Roland Emmerich knew that it wouldn't in real life. In reality, the statue isn't all that strong; even in a gust of wind, the arm of the statue sways 8 feet from side to side. And yet all of the buildings are gone in whatever horrible disaster occurred, and the flimsiest structure in New York outside of a billboard is still standing.
Corrected entry: In the scene after the hunt when all the humans are being rounded up, we see a group of gorillas posing for a photo with there feet on a stack of dead humans. If you watch the scene unfold as the camera passes over the pile of people someone in the stack moves their legs just in time to be picked up by the camera.
Corrected entry: All of the evolutionary and geographical changes are supposed to have happened within a 2000 year period? It would take hundreds of thousands, if not millions of years for those changes to occur, no matter what the nature of the catastrophe that had befallen the Earth.
Corrected entry: In the scene where Taylor is on trial, and first starts talking, the three seated officials assume various poses - the one on the left with his hands over his eyes, the middle one with his hands over his ears, and the one on the right with his hands over his mouth. A nod to the see no evil, hear no evil, speak no evil monkeys.
Corrected entry: This is a mistake between the first 2 Apes films. In the beginning of the first Apes movie as the ship is sinking Taylor looks at the Earth time chronometer and it says 11-25-3978 as the date. In Beneath the Planet of the Apes Brent tells his skipper that the year is 3955. They were following Taylor's trajectory and Brent does meet Taylor but according to the second film Brent got there 20 years earlier than Taylor.
Corrected entry: At the beginning, when the hatch is blown on the ship, you can see both windows blow off the ship and a piece of the nose by the window almost blow off. Looks like the special effects department got a little carried away with the explosives.
Corrected entry: At the end of the movie when Taylor is shooting the Apes one of the chimps protests, and as he does you can see a hole in his costume, where you can see his Human thumb.
Corrected entry: Early in the movie right after the 3 astronauts run from the rolling boulder they are sitting down under another rock (taking a breather) and Landon is speaking to the other two guys. You can tell from the long camera shot that there is no way he could be speaking those lines with that kind of thought and emphasis because he is in the middle of wrestling with his backpack and sitting down at the same time he is supposedly making some grand observation about their predicament.
Corrected entry: At the end of the movie, just before discovering the ruins of the Statue of Liberty, the horse and riders are traveling along the beach. If you look closely, you can see a parallel set of hoofprints in the sand. Apparently the surf didn't wash away the evidence of a previous take.
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.
Corrected entry: The astronauts should had immediately realized they were back on Earth, at the beginning of the movie, if they had only gazed at the Moon or constellations in the night time sky (even if it was the year 3978). Naturally that observation would have made that a different movie.
Corrected entry: Early in the movie, Taylor yells for someone to "blow the hatch before the power runs out". The hatch is blown, and seconds later the power goes out. As everyone abandons the ship, Taylor looks over at the digital "Earth Time" clock to note the date (11-25-3978). With the power out, the clock obviously wouldn't have been illuminated.
