Fantasy is a genre that uses magic and other supernatural forms as a primary element of plot, theme, and/or setting. Many works within the genre take place on fictional planes or planets where magic is common. Fantasy is generally distinguished from science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three (which are subgenres of speculative fiction). In popular culture, the genre of fantasy is dominated by its medievalist form, especially since the worldwide success of the The Lord of the Rings by J. R. R. Tolkien. In its broadest sense however, fantasy comprises works by many writers, artists, filmmakers, and musicians, from ancient myths and legends to many recent works embraced by a wide audience today.
