Red Herrings

A red herring refers to a device or diversion used to distract the onlooker from the original idea. Red herrings are often seen in films, adventure games, and puzzles. 

In films, a red herring can often be found in Alfred Hitchcock stories, where characters and things turn out to be anything but what the viewer expects them to be. One of the best examples of the use of a red herring in modern film can be found in the film Saw. During the whole film, two characters spend time imprisoned in a room in which a third character lies dead. Throughout the film, both characters appear to be guilty of a series of murders, until is discovered at the end that the third person in the room is not actually dead. He is, in fact, the killer.

In the Bodyguard the red herring is the creepy stalker guy, who everyone assumes is the killer. However the real killer is a hit man hired my the targets sister!

This is the stalker who is believed to be the killer.              

This is the actual hit man who is not even suspected until the final moment.
