The astronaut isn't the hero here. He is the monster. Chuck, armed with a video camera and a flag-planting mission, suddenly finds himself running for his life through a world where he is the terrifying extra-terrestrial. This meta-narrative allows Planet 51 to satirize decades of Cold War sci-fi paranoia, suggesting that from the outside, humanity’s need to explore and conquer might look monstrous.
