Who has done it? This is a question at the center of many a story. You may know it as a “Whodunit?” There are mystery stories where you as the reader or the viewer doesn’t know who committed the crime, usually a murder, and the story involves a character or characters trying to figure it out. Maybe you can figure out whodunit yourself, and maybe you can’t. These are different from shows like “Columbo” where you know who did it but the point is finding out how Columbo will figure it out for himself and catch the criminal. We aren’t talking TV, though. We’re talking film. Here are 25 of our favorite Whodunit movies. The genre is a little nebulous, but we feel these all make the cut.
