2. Unreliable narrator

The use of an unreliable narrator may seem common today, but in 1950, films were presented from a more objective point of view .This allowed audiences to see the characters as they were or how the filmmakers intended.

Today there are many examples of movies with multiple perspectives. A notable modern riff on the Rashomon Effect that utilizes the unreliable narrator can be found in the 2014 film Gone Girl.In this mystery thriller, a man becomes the suspect in the disappearance of his wife. 

As he becomes less reliable throughout the story, we become more engaged in finding out the truth.
