Christian Heinke, a novelist from Bochum, discusses the challenges of adapting Max Brooks' "World War Z" into a Hollywood film, noting that significant changes are often necessary due to the differences between novels and movies. He highlights the difficulty of translating the book's documentary style and multiple perspectives into a film, acknowledging the need to focus on a hero's journey for broader appeal. Despite the risk of losing the book's essence, Heinke remains optimistic about the film's success and expresses openness to a film adaptation of his own work.
