This shows us that these guys are dominant as the camera shows the subjects as one behind the other diagonally. This shot is a medium close up as you can't see their waists, just slightly but you can see there shoulders upwards. Also there is a chase about to happen and so it shows Tom Cruse's perspective and then these guys perspectives to show a threat or danger.

This shot shows a rusty old car in the middle of an ally way. Also you can just about see Tom in the background. This is a long shot because you see head to feet. Again this shot shows a chase about to go down and tom runs past whilst the camera pans horizontally.

This shows another medium close up of Tom and the reason they have used this is it shows the full emotional feelings of the main character. You could say he is thinking but you could also say that he knows he could be in danger as lots of his enemies suround him. But to point out he is the MAIN character he manages to find his way out.
