Film Noir alters the perception of characters.

In the Film Detour one of the very first stereotypes of Film Noir is the Omniscient Narrator and the Flashback. This is shown by the main character Al Roberts and his down on luck attitude in the beginning of the movie. This is very reminiscent of one of the more famous movies in the Film Noir Citizen Kane were their demise is shown early on. Even though in this case we don't learn of his full demise until the end Al Roberts shows his distress by being like Eeyore in every way and seems to hate the world. He then tries to convey to the audience his side by narrating his story in a flash back which last for 90% of the movie. He begins to try and show how he is out of luck and his girl has left him to go to L.A. He decides to go after her and that’s when things hit the fan. After finding a car ride to Los Angeles after days of hitch hiking he gets into a predicament when Charles Haskell Jr., the car owner, passes away in his sleep. Trying to convey his innocence he reasons with the audience that no one would believe him and hides the body and takes his personality. Thus following the stereotype of Film noir, he pours his conscious out to the audience while going against what is right. Though now a days with CSI and the NSA im sure Gibbs could have saved him. Anyway this stereotype runs right along with the movie with Roberts trying to reason what he had to do. And through his conscious he is kept under Vera’s finger nail because he knew leaving Haskell Jr. there was wrong. In the end it shows his ultimate demise being taken to jail where his final plea is said to the audience “Fate, or some mysterious force, can put the finger on you or me for no good reason at all”.
