Kenneth Branagh's A Haunting in Venice is a thrilling entry in the whodunit genre, but there are plenty of other quality films similar to it in premise. While British writers Sir Arthur Ignatius Conan Doyle and Agatha Christie are among the most recognized writers in the whodunit genre, their novels and characters have inspired thousands of writers worldwide. Tropes commonly associated with the whodunit genre include but aren't limited to hard-boiled detectives, intricately complex plots and twists, and clues hidden throughout the movie to offer readers/viewers hints as to who the story's killer might be.
