Based on the graphic novel by Scott Mitchell Rosenberg, Cowboys & Aliens starts in 1800s Arizona, where the local cowboys and the indigenous Apache tribe have been feuding fiercely for quite a while. Their skirmish is interrupted, however, by the appearance of a spaceship, commanded by an alien creature that's bent on enslaving the human race. It's time for a six-gun shootout between these cattle rustlers and space invaders, and there might even be a temporary peace between the cowboys and Indians as they both take aim at these extraterrestrial uninvited guests. ~ Cammila Albertson, All Movie Guide
