Literature, science, cinema, comics, exhibitions, role-playing games, video games and the Asian center: for more than 20 years, the multidisciplinary programming of Utopiales has brought together the worlds of science and science fiction. After more than 1,067 films screened, 2,500 authors, designers and researchers invited and nearly 170 exhibitions and artistic installations scheduled, this uniqueness makes the Nantes festival an essential event of its kind in Europe and across the Atlantic.
