Walk On The Wild Side directed by Edward Dmytryk

camera
the camera is used just like any other thriller it is iconic to see tracking and panning in an opening of a thriller film it crates suspense and keeps the pace of the edit slow, the types of shots used are close up and mid shots this is also a common technique such as seen in "Sin City" ,close ups crate a connection with the audience and establishes character as well as help create mood, tracking seems to be a main convention in the thriller genre it is seen in many films such as Alfred Hitchcock's , a big thriller film director, "citizens Kane" where we see tracking of fencing and panning inside the house "citizens Kane" is a brilliant example for lighting and camera use for a thriller genre.
editing
like wise with the cameras slow paced editing is used to keep the pace slow and flow fluently to do this dissolve cuts are used which is yet again iconic to the genre however later in the opening extract a fast paced edit is used when the cats fight this shows how the genre is an action thriller and this technique of having a fast paced scene seems to always happen in thriller sub genres such as "I Am Legend"
mise en scene
there is a lot semiolidgy in the extract it starts with binary opposition with black and white being the cat black walking through white surrounding this could show how in every normal setting such as a place of work or in a person i.e a city there is always a "wild side" underneath liking the title with the narrative, another iconic signifier is the cats eyes when the e.c.u is used on the cats eyes it reflects a sense of mystery and unknown as well as the cat being fully black it symbolises danger and death, going back to the idea of a wild side in a location or person we see tracking of a fence with the cat going in front and behind using a dissolve cut inbertween this could reinforce the idea of how as a person there is always that underlining idea and need to brake the rules and go past that barrier weather it be in society or life in general.
