Agatha Christie's mystery novels have been adapted to the movie screen since the late 1920s with varying degrees of success and accuracy, however, the upcoming horror film A Haunting in Venice may be the wildest Christie adaptation yet. A Haunting in Venice is based on Agatha Christie's 1969 novel "The Hallowe'en Party." It follows Hercule Poirot, Agatha Christie's long-running Belgian detective, as he attends a spooky Halloween night séance in a haunted palazzo in Venice, Italy. A Haunting in Venice's cast is led by Kenneth Branagh as Poirot, along with Kelly Reilly, Michelle Yeoh, Jamie Dornan, and Tina Fey.
