The best Science Fiction is never about outer space or time travel. Those are the things that give the film free license to talk about deeper subjects that no one would sit and watch for 2 hours.
This is one of the best science fiction movies ever. But it's not about space or apes or time travel or any of that stuff. Filmed at a crucial moment in American race relations history, Planet of the Apes is about giving black people equal rights. But I should let you figure that out by yourself.
Innovative music score that set the bar to new heights with dramatic percussion taking the lead and brass accents that evoke goose bumps is by Jerry Goldsmith.
Astronauts crash on a planet and find out that Apes are the dominant species while humans graze amongst the simian's crops.
When Astronaut Taylor gets captured and sent to the chimpanzee scientist Zira to be tested , she discovers the Earthling can speak, which men on their planet don't have the ability to do. Before long the leaders of society are shocked to learn that Men and Apes might be equal!
Lots of chases and cool sets make this imaginative picture fun to watch.
