Generic Conventions Of Film Noir: This gun for hire.

This gun for hire

Today we watched the first 5 minuets of a film from 1942 called "This Gun For Hire", 

In the opening scene to the film had a alarm clock sounding and the main actor/ character waking up, I think that the sound of the clock is non-diagetic as it was a sound you could see (you could clearly see where the sound was coming from), also in the opening few moments of the film, the man smacked the woman (seemed like a cleaner or something like that) because she tried to remove the man's cat from the room and he wouldn't allow it.

One shot that I noticed was one where the actor looked at the camera as if it was a mirror (conveying the message that there should be a mirror in the place of the camera).

Also in the opening scene there was a piano playing in the background, as you could not see who was playing it or where the piano was in the first place, it leads me to think that the sound was diagetic.

A few minuets later I noticed that, in a kitchen there was a kettle whistling, this was a non-diagetic sound.

Below are pictures of an A3 piece of paper that has been folded in half, on one side are all the Generic conventions of Film Noir and on the other side are all the non-generic conventions of film Noir.

Below is the other side of the A3, this time it was all the non-diagetic conventions of film noir.
