The best and most divergent of Kenneth Branagh's films dedicated to the work of Agatha Christie. It adapts very loosely the penultimate novel of her most iconic character: the Belgian detective Hercule Poirot. Branagh's greatest achievement is to imbue the usual detective story with a ghostly atmosphere and set it in the mysterious Venetian setting. This third installment is equal parts murder mystery, old-fashioned ghost story and supernatural thriller, and Kenneth Branagh perfectly exploits the horror tropes with which he enhances the familiar whodunit narrative, beautifully shot by cinematographer Haris Zambarloukos . It is an absolute winner.
