Tommy joined PEOPLE in 2022. People Editorial Guidelines Published on September 12, 2023 12:00PM EDT Tina Fey joins Kenneth Branagh's detective Hercule Poirot as another classic Agatha Christie character in A Haunting in Venice. On Tuesday, 20th Century Studios shared a clip from the movie exclusively with PEOPLE, showcasing Fey, 53, as a fictional mystery novelist named Ariadne Oliver as Poirot begins to lay out his investigation for yet another case. In the clip, Poirot notes that Ariadne was the first person to notice the dead body at the center of A Haunting in Venice's mystery. He then admits the mystery writer has a credible alibi and asks her to assist him in his latest investigation, a testament to a shared history between the two characters. A Haunting in Venice marks Branagh's third movie adapted from Christie's Hercule Poirot novels, following 2017's Murder on the Orient Express and 2022's Death on the Nile. The new film is adapted from one of the author's lesser-known novels, Hallo'ween Party, published in 1969.

Rob Youngson/20th Century Studios A Haunting in Venice also stars Michelle Yeoh, Kyle Allen, Camille Cottin, Ali Khan, Emma Laird and Riccardo Scamarcio. Jamie Dornan and Jude Hill, who starred in Branagh's Oscar-winning 2021 movie Belfast, play another father-son duo in the movie as well. Fey's character Ariadne appears in a number of Christie's novels, including six featuring the detective Poirot. Christie's official website says the character is "in many ways, a vehicle for Agatha Christie’s own voice, particularly in relation to writing and the public," though Christie herself never admitted the character had more than "a strong dash" of herself. Prior to Fey taking the part, Ariadne had been portrayed on screen by Jean Stapleton, Julia McKenzie and Zoë Wanamaker in a number of Agatha Christie adaptations. A Haunting in Venice is in theaters Friday.
