A Haunting In Venice (2023)

Directed by and starring Kenneth Branagh, A Haunting in Venice brings Hercule Poirot to post-war Venice for a murder mystery inspired by Agatha Christie’s Hallowe’en Party. When the retired detective attends a séance at a decaying palazzo on Halloween night, one of the guests is murdered and Poirot must investigate amid claims that the house is haunted. Tina Fey, Michelle Yeoh and Kelly Reilly co-star in this darker Poirot mystery, which combines a classic whodunit with eerie supernatural atmosphere and a haunted-house setting.
