Planet of the Apes
Planet of the Apes features one of the most iconic endings in cinema history. A group of astronauts awakens from deep hibernation after a space voyage, and their spaceship crashes into a lake on an alien planet. At the end of the film, as Taylor and the formerly-captive Nova follow the shoreline on horseback, they discover the remains of the Statue of Liberty—meaning that the "alien" planet upon which the astronauts crash-landed was actually Earth after a nuclear war.
