MOIDER! A movie mystery is nothing without a cunning villain, and this motley crew of killers are so devious they were concocting schemes and spinning yarns right under our very noses until it was almost too late.
Figuring out exactly who murdered Colonel Mustard with the lead pipe in the library is all part of the fun when it comes to movie thrillers, but not everyone can spot the clues in advance. If you're fed up with face palming every time you get duped, here's a tip: movie bad guys can't use iPhones, so if you see a suspect with one, look elsewhere, because you're definitely getting colder.
For the most part, filmmakers want to keep you constantly guessing until the big reveal, yet there's ALWAYS a telltale detail that points to the murderer, hidden in dialogue or brazenly dropped in the background of scenes that we all managed to miss.
