Told in Graham Humphreys' own words and through a series of intimate conversations, Captured Souls explores the life and legacy of the UK's most iconic horror illustrator. From a childhood marked by a haunting Ladybird skeleton to the gouache-drenched goth era of Evil Dead and Nightmare on Elm Street, Graham reflects on a career that has defined horror for generations. Featuring discussions with Reece Shearsmith, Andy Nyman, Madeline Smith, Alan Jones, and more, the film charts a vivid time line through banned video sleeves, goth clubs, iconic posters, and the rediscovery of a lost original.
