The Usual Suspects

McManus

My first impressions of McManus were that he was a tough, rude and lazy character.
With regards to the mise-en-scene of the shot, we can see that he is lying in bed in a dirty room, probably one that he rents for very little, whilst all of the other suspects are up and going about their daily business.
A medium shot allows us to see McManus, his set up, and the police who surround him on all sides.
He swears at the men when they try to arrest him and refuses to go with them, resulting in a forceful capture on their part, as they have to drag him out and keep a hold on him.
This suggests that he is dangerous and does not care for the authorities.
We only get to see half of his face in this shot (the camera doesn't change its angle throughout the scene), and we can see that he has tattoos across his arms, which also adds to the danger surrounding him and his careless attitude.

Hockney

We are introduced to Hockney for the first time whilst he is tampering with a car in a garage (probably illegally).
This makes him seem strong, and also shows us that he has access to a lot of tools of which he could use as weapons, thus making him seem a more threatening character; and as he reaches underneath the car for something, the police become uneasy.
The medium shot used allows us to view Hockney's face, and also the police behind him; the police, though, cannot see his face, which gives us an advantage and adds to the tension of the scene.
As he is in a better position than the officers, they feel obliged to surround him at once, and Hockney says, "Sure you brought enough guys?", which ends the scene.
This suggests that he is confident in himself and could become a real threat to the others.

Fenster

Upon seeing Fenster for the first time, I thought he looked like a stereotypical gangster.
We see him wandering down a rough street, dressed in a dark, flashy suit, which makes him seem like he means business; although, as he starts to pace back again, we realise that he is actually trying to get away from someone, and is not as confident as we initially anticipate.
Tracking shots are used to follow him on his path, and we then see a police car come into view, which then explains Fenster's tense composure.

The non-diegetic background music mirrors the way he moves, and I think the producer did this to make us feel more anxious for him.
He is arrested pretty easily and doesn't seem to even think about protesting, thus lowering our opinions of determination.

Keaton

Keaton seems to be the most important of the delinquents, as he is filmed for a longer period of time than the others.
He is in a meeting at a restaurant when the police come to arrest him, which makes us question as to why he has stolen a truck filled with guns, as he seems to be doing quite well for himself in regards to money, already.

He looks better dressed and wealthier than the others, and we can see that he is entertaining guests of his, including what looks to be his girlfriend, which makes it seem as if he has a better reputation to uphold, and when the police make themselves known as present, we see a close-up of Keaton's devastated expression; much like Fenster, but maybe caused by different reasons, such as his reputation.
I think the producer made him seem almost innocent in this scene, so as to make the audience think that he is not going to pose a threat, although he could be the man in charge of an illegal corporation, for example, as no one would ultimately suspect him as being related to crime.

Verbal

The last of the suspects is quite different to the other four, as he dresses more timidly and walks with a limp.
A close-up focuses solely on his limp, making sure that we are aware of this for some particular reason, maybe to identify him later in the film; this also makes us believe that he is not capable of committing any crimes and that they must have accused the wrong guy.

We want to know what kind of evidence they have against him, as it does not make any sense for him to be there with the other four who seem to fit the category of 'criminal'.

We see him walk into the police station, only, where we hear his confused thoughts, rather than hearing him speaking to one of the characters, which reinstates our own similar confusions, too, and separates him from the rest.
He is also the only character of which we don't know his background.
