Hercule Poirot Movies: Modern Era
Kenneth Branagh's contemporary take on Hercule Poirot brings a darker, more psychological approach to the character while maintaining Christie's intricate plotting. Beginning with his 2017 Murder on the Orient Express, this trilogy features Branagh as both director and star, creating a unified vision with subtle character development across the films.
Unlike previous adaptations, these films contain loose narrative continuity, with occasional references to past cases and a gradually evolving portrayal of Poirot's emotional journey. Each mystery remains self-contained while contributing to an overarching character study.
