"A Haunting in Venice" is a 2023 American mystery film produced and directed by Kenneth Branagh from a screenplay by Michael Green, loosely based on the 1969 Agatha Christie novel "Halloween Party". It serves as a sequel to "Death on the Nile" (2022) and is the third film in which Branagh reprises his role as the Belgian detective Hercule Poirot. The film is set in post-World War II Venice, where Poirot, now retired and living in his own exile, reluctantly attends a seance. However, when one of the guests is murdered, it is up to the former detective to once again uncover the killer.

The ensemble cast includes Kyle Allen, Camille Cottin, Jamie Dornan, Tina Fey, Jude Hill, Ali Khan, Emma Laird, Kelly Reilly, Riccardo Scamarcio, and Michelle Yeoh. The film was released in the United States on September 15, 2023, by 20th Century Studios. The film received generally positive reviews from critics and has grossed $102 million worldwide.

According to the trailer and reviews, the film has a spooky and dark atmosphere, with horror elements and a haunted-house thriller vibe. The palazzo where the seance takes place is rumored to be haunted by the vengeful ghosts of children who died there years ago during an outbreak of the plague. The violence in the film pushes the PG-13 rating to its breaking point. The film is also described as an empathetic portrayal of the death-haunted mentality of people from Branaghs parents generation who came through World War II with psychic scars, wondering what had been won.
