Analysing openings of 'The silence of the lambs' and 'The usual suspects'

Today in our media studies lesson, we watched the openings of both 'The silence of the lambs' and 'The usual suspects', after which we were given an assignment to analyse the opening of these thrillers:
In 'The silence of the lambs', there are many aspects of the opening scene, which make it a good thriller. The scene starts off with a Jodie Foster running through woods. While this is done, there is slightly eerie non-diagetic music being played. This, together with the steady cam being used gives the audience an impression that something's wrong. The steady cam being behind her is a very effective method to use as it gives the idea that she is being chased and she's in danger. As the music becomes slightly faster, the camera starts to track Jodie Foster to make the visual effect of her running faster. The title (The silence of the lambs) displayed while she is running is also effective in setting a thrilling atmosphere as the title is in harsh, bold, formal text. As she is climbing over the obstacle, she appears to be taller, which gives the audience a sense that she's now not as vulnerable. After she speaks to a member of the FBI and there is a shot showing 'FBI' on his hat, viewers will be confused because they will feel she is now safe, which is a big contrast. The non-diagetic music is also changed, which establishes she is not in danger. When the scenario changes and she is in an office building, everyone is wearing uniform which shows a sense of security. Although she is quite small compared to other people in the building, she is still looking powerful as the camera is mostly focusing on her by slowly following her movements. There is creepy music (slightly more eerie than before) when she is looking at the photos. This is an impression that the photos may be linked to something bad that will happen.
The other film's opening that we watched was 'The usual suspects'. There was not as much key techniques used as there was in 'The silence of the lambs', but there were some techniques used that I found interesting.
As the scene starts, there is a slow mood, the music playing is slow and the font also appears slowly, which creates a calm mood. This contrasts with later on when there is a man shown in black clothing, who looks like an antagonist. The choice of colour for the clothing was good as black usually symbolises evil in thrillers. More eerie music is played when he is shown to further make him look like an antagonist. He looks like the dominant character in this scene because when he is standing up the stairs, there is a low-angle shot looking up at him. The camera is also following his movements making him look important.
Overall, I think both these openings are interesting in terms of the techniques they used.
