A Haunting In Venice is the third movie in Kenneth Branagh's Hercule Poirot series, and the trailer hints at it being the best movie in the franchise yet. Branagh has a clear love of the Agatha Christie novels, as the filmmaker directed Murder on the Orient Express and Death on the Nile, and he throws himself into the world, absolutely hamming it up as Poirot. Along with Adam Sandler's Murder Mystery series and Knives Out, Kenneth Branagh is to thank for the revival of the murder mystery genre, as Murder on the Orient Express made a huge $352 million worldwide (via Box Office Mojo).
