There's something uniquely thrilling about a whodunnit. Unlike other mysteries, these stories lay out the suspects and clues right from the start, inviting you to play detective alongside the characters. The best whodunnit movies are those that keep you guessing until the very end, with twists that feel earned and resolutions that satisfy. Whether you're a seasoned mystery buff or just dipping your toes into the genre, these ten films are perfect examples of the craft.
The Thin Man (1934)
Based on Dashiell Hammett's novel, The Thin Man is as much a comedy of manners as it is a murder mystery. The chemistry between William Powell and Myrna Loy as Nick and Nora Charles is electric, but the central puzzle is no slouch either. When inventor Clyde disappears after a confrontation with his mistress, the former detective and his socialite wife are drawn into a web of deceit and murder. The film's lighthearted tone and classic gathering of suspects in the finale make it a joy to watch.
And Then There Were None (1945)
Agatha Christie's most adapted work gets a stellar treatment in René Clair's 1945 version. Eight strangers are lured to an island mansion by a mysterious host, only to be killed off one by one. Each guest has a dark past, and as the body count rises, paranoia takes hold. This film set the template for countless whodunnits to come, and its mystery remains gripping decades later.
The House of Fear (1945)
Sherlock Holmes, played by the iconic Basil Rathbone, takes on a case involving a group of men living in a Scottish castle. When members of the Good Comrades begin dying after receiving envelopes of orange pips, Holmes must unravel the deadly pattern. While not the best of the Rathbone series, this film is a solid whodunnit that showcases the detective's deductive brilliance.
The Last of Sheila (1973)
Co-written by Anthony Perkins and Stephen Sondheim, this original whodunnit was inspired by real-life scavenger hunts. A group of Hollywood elites gather on a yacht for a mystery game that turns deadly when their host is murdered. The film's clever script and stellar cast, including Dyan Cannon and James Coburn, make it a must-see. Its influence can be seen in modern mysteries like Glass Onion.
Murder on the Orient Express (1974)
This adaptation of Agatha Christie's classic features an all-star cast and a plot that is the epitome of the whodunnit form. When a passenger is found dead on the famous train, detective Hercule Poirot must interrogate a train full of suspects. The film's elegant pacing and shocking conclusion make it a benchmark for the genre.
These films, along with others like Hot Fuzz and Clue, prove that a well-crafted whodunnit can be both intellectually stimulating and wildly entertaining. For more great mysteries, check out our list of The Most Subversive Thriller Movies Ever Made, Ranked.
