Like science-fiction literature, science-fiction operas may be set in the future and involve intergalactic travel or alien invasion. Other science-fiction operas focus on a dystopian view of the future. Like Lorin Maazel's opera 1984, they may be based on a previously written science fiction book." ] ,
