Boyz n the Hood director John Singleton is set to direct his first science fiction film, Executive Order. It's typical alien-invasion fare, with a plane crash unleashing a space monster that terrorizes a snowbound small town. Still, Singleton's got the violent-action chops to make it work: his remake of Shaft may have bombed at the box office, but it was still badass. Singleton's also attached to direct the inner-city superhero film Luke Cage.
