Science fiction uses codes like filming in outer space or future settings to signal that the story is not realistic but could be possible in the future. The target audience for science fiction is typically males as the genre often depicts technology and space exploration in a way that relates more to men. Science fiction challenges viewers' ideas about humanity and the world by exploring concepts like life on other planets or advanced technologies not yet developed. Creating science fiction films requires substantial investments in technology, special effects, costumes, makeup, casting, and settings to bring the imagined futures and worlds to life in a believable way for audiences.
