10 Movie Murders That Were Utterly Impossible To Solve

9. Se7en

Spacey is a bugger for this last minute twists. His appearance in David Fincher's first bonafide classic Se7en, that darkest of serial killer movies, was a surprise to everyone - the star actor's name wasn't included in any promotion for the film, and is absent from those haunting opening credits to boot. Which makes it all the more frustrating, watching the investigations of Brad Pitt's Detective Mills and Morgan Freeman's Somerset into a series of murders that follow the Biblical Seven Deadly Sins, and they don't actually solve it. The answer falls into their laps, as Spacey's John Doe surrenders to the police. It's all part of his plan... Obviously, you're not supposed to solve the mystery in Se7en. The film turns the traditional whodunit narrative on its head, because it isn't a whodunit - it's debatable as to what it actually is. A darker-than-dark thriller? A horror film? Some sort of psychological torture? The confusion that follows the investigation and the subsequent surrender is mirrored with the audience's reaction, since they can make as much sense of the murders and Doe's sudden appearance as Mills and Somerset do. There are barely even any suspects until he shows up, bleeding from the fingertips, at the police station. Se7en is about as far away from Miss Marple as you can get, in every conceivable way.
