The Third Man (Analysis)

This part of mise-en-scene would be the location/background. It shows demolition which makes the atmosphere very mysterious and gives a sense of suspense which is perfect for a thriller film as it raises the questions of what? why? when? who? where? how? This is perfect for any thriller film because it gets the audience guessing and trying to figure things out just like a thriller film should. Although, typically thriller films mislead you right until the very end. 

This photo of his fingers coming up through the drain is a camera angle as it's focused on his fingers but you can also see the mysterious deserted background that typically for an old thriller film is dark, wet and the floor is cobbled stones. The fingers through the drain actually show concealment as we don't see the person's face and so it creates a tense moment for the audience in trying to figure out if they know who the character's fingers they are.

The prop use of the gun gives the audience a sense of what the plot will be about without even watching any of it. We know it is more likely to be a crime/police thriller than a psychological thriller for example. Also, with the prop being a gun, we could assume that there might be a police chase or gun fight of some kind which is very classic thriller.
