In the movie Alien, we know that the actual alien or aliens are vicious killers, but creepy they most definitely are not. The creepiness comes from the androids produced by Weyland Industries to serve the human crew on board the ship. This is David; he looks okay at first, but there is something in there working away but is it good, bad or just downright evil?
Here is why we cannot wait to for Prometheus;
In the distant future, two superpowers control Earth and fight each other for all the solar system’s natural resources. When one side dispatches a team to a distant planet to terraform it for human colonization, the team discovers an indigenous race of bio-mechanoid killers.
Ridley Scott, director of ‘Alien’ and ‘Blade Runner,’ returns to the genre he helped define. With PROMETHEUS, he creates a groundbreaking mythology, in which a team of explorers discover a clue to the origins of mankind on Earth, leading them on a thrilling journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race.
