• Hard-to-Adapt Work: The Murder of Roger Ackroyd fundamentally relies on several quirks of the First-Person Perspective narration (specifically, the story is an account written in first person by the murderer himself). Consequently there have been few adaptations despite it being one of Christie's most famous books, given the difficulty of translating the twist into live-action. This film manages this by making the first 3/5 of the movie a Whole Episode Flashback. At the start of the film Shiba/Sheppard gives Suguro/Poirot the manuscript that Shiba has been writing. This is a scene taken straight from the novel, but in the book it's not until near the end that Sheppard gives Poirot the manuscript and lets him read. The simple device of starting the movie with this scene allows most of it to take place with Shiba's narration accompanying the action, which preserves the impact of the twist.
