Reportedly the author’s first — and possibly future-defining — brush with Hollywood studios came following talk of his fourth Discworld book, 1987’s Mort (which centered on his character Death) being picked up for adaptation. Allegedly, after research from focus groups, he was asked to “lose the Death angle.”
