It's the biggest celebration the British Film Institute has ever held with talks and classic science-fiction movies from War of the Worlds to 2001: A Space Odyssey being performed everywhere from in pubs to planetariums.
The BFI's Days of Fear and Wonder season begins across the region this weekend and, as Andy Dickenson found out, two of the world's greatest sci-fi authors were inspired by a small village in the heart of Sussex.
He speaks to Michael Sherborne, H.G. Wells' biographer; Dr Benjamin Noys, from the University of Chichester; and Ellen Cheshire, of Film Hub South East.
