Whodunits are movies that center around a murder mystery. There’s always someone investigating the murder and attempting to find the killer before they strike again. They contain several twists and turns and keep audiences guessing. Whodunits have been around for years, but with the making of movies such asKnives OutandSee How They Run,they’re rising back into popularity.

Whether it’s through dialogue or sets, some movies cleverly give away the killer right under the audience’s nose. Some, likeMemento, secretly tell exactly what happened before the killer is officially revealed without anyone noticing.
