Book excerpt: Through spaceships, aliens, ray guns and other familiar trappings, science fiction uses the future (and sometimes the past) to comment on current social, cultural and political ideologies; the same is true of science fiction in children's film and television. This collection of essays analyzes the confluences of science fiction and children's visual media, covering such cultural icons as Flash Gordon, the Jetsons and Star Wars, as well as more contemporary fare like the films Wall-E, Monsters vs. Aliens and Toy Story. Collectively, the essays discover, applaud and critique the hidden--and not-so-hidden--messages presented on our children's film and TV screens.
