Japanese artist Hajime Isayama's Attack on Titan series of graphic novels has made him a global bestseller and a cult figure.
His dystopian vision of maneating giants stalking humanity has now been made into a bigbudget live action film.
In an exclusive interview with the BBC, the reclusive artist revealed his inspiration, and how he nearly gave up after publishers told him he was not good enough. Film footage courtesy of Hajime Isayama, Kodansha/Attack on Titan Production Committee
