How does the Chase sequence and the Opening of the Third man use Framing and Composition techniques and Mise En scene to create meanings and metaphors?

Figure 1 

In figure 1, there is a distinctive strong shadow composed via Chiaroscuro lighting which means a strong contrast with light and darkness. The way in which the lighting is constructed is through Key lighting. By using key lighting it amplifies strength in which contrasts are constructed, additionally, this is also created via the use of no Fill or back lights. A fill light is used to fill in darkened shadows, and a back light highlights the background, however, as figure 1 shows, this is not wanted for the effect its trying to put forward. The overall effect of using specific types of lighting for this shot is the intense contrast of light and dark, the dark shadow portrayed on the wall could be exhibiting the visualization of the protagonist's villainous personality running away into the light. Furthermore, figure 1 appears to have vanishing points (point where disappeared off the frame) This is where an audience is automatically captivated to look, a vanishing point is used to draw an audiences attention elsewhere within a frame, leading you to potential disorientation.
                                                                                       
                             

Figure 2 

Furthermore, figure 2 represents that the post is central within this shot which highlights its significance, this is done via the use of back lighting which gives us this focal point. The fact that it is within the center of the frame could suggest that it's foreshadowing something for later on. Additionally to this, you could interpret the post to signify good and evil, the fact that it to also uses chiaroscuro lighting leads us to see the contrasts within the shadows. With the pavements being covered with rain, it symbolizes the bleakness of that area which could provide you to believe about the evil within.   

Figure 3 

Arguably, figure 3 connotes the idea of the evil within, this is demonstrated through the shot being very angular with the straight edges which can be seen along the beam. This implies evil as angular shots originally developed from German expressionism which came around in the 1930's-1940's when people were fleeing from Germany to go to places such as America. Subliminally, directors at this time were trying to incorporate the evil within into their films, so by using particular shots such as the angular one, it gives the audience a heightened suspense of terror. Moreover, the shot is also titled, so when people first see this shot they themselves feel the perplexity of it, which could be entailing the confusion of the character himself, also, we know that the character has a strong sense of disorientation as in this particular scene, the man within the frame points up for hell and down for heaven, contradictory to that, we as an audience know this is incorrect, perhaps even suggesting the confusion between the protagonist's (Harry Lime)  good and evil side. Likewise, chiaroscuro lighting is used again to construct the shadow that lurks above the door way, again suggesting that there is evil within. The fact that this shadow takes place above a doorway could imply that maybe its an entrance into an evil/bleak world. Figure 3 is a prime example of how meanings and metaphors can be formulated to give many various effects.

Figure 4 

Intense chiaroscuro lighting can be observed from figure 4, again, this is used to create the strong contrast in shadows and give a sense of moral ambiguity. The shadows depict the re-occurring theme of  fear of evil that ran through out Vienna, Austria where this film is to be set in. During world war 2, Vienna was heavily bombed, so went from being a place with lovely scenery, to being destroyed which can be reflected upon through the bleakness of the shadow. Also, the vanishing point in figure 4 draws our attention to the edge of the scene, where the balcony is; this particular balcony is very decorative, which could create connotations of   Vienna once being a place with extravagant buildings, and having the contrast of the shadows glaring through could also employ the divergence of Vienna post and pre-war. Additionally, stair cases could be symbolic for the theme of heaven and hell as its always been dictated through history that when you go to heaven you climb up the staircase to get to it, therefore, this can noticeably be seen within the film The third man.
