Blending live action with animation and adapting a novel by Anthony McCarten, DEATH OF A SUPERHERO follows the fate of typical 15-year-old Donald (Thomas Brodie-Sangster). Donald has issues with his parents, his school and would-be romantic relationships, all the while nurturing a burgeoning artistic talent. But his perspective changes when he is diagnosed with cancer. Left bald and gaunt by chemo, Donald retreats into his own world, where he becomes an invincible superhero. Helped by a psychiatrist (mo-cap maestro Andy Serkis), his parents and the girl he falls in love with, Donald decides to make the most of his remaining days.
