Sound
The beginning of the clip stats with just diegetic sounds such as the buzz from the TV and the car turning up, however this then changes to non diegetic sounds such as the drumming beat and then increases to a fast beat. This makes the audience more tense and wondering what is going to happen next. As the tension increases the music becomes more dramatic and faster. This plays on the audience's feelings of apprehension and confusion as they wonder what is about to occur next.
As Lau is talking and explaining about how the police are planning to seize their funds, the film shows the police raid the bank. This makes the audience see what the police are doing and hearing why it won't work from the Lau through the TV. This makes the audience realize that even though the police have the right idea they are not going to be able to seize the money as it has already been moved to a more 'safer alternative'. This makes the audience then wonder if the police will ever succeed.

Lighting
In the beginning the room with all the people in is shown to be darker than where the police are which gives an indication to who the 'good guys' are and who are the villains. Strangely it seems that the second the Joker walks into the room instead of the previous lighting, it turns brighter which puts contrasts to the Joker's(Heath Ledger) body which gives the illusion of a silhouette. This makes the audience weary of the Joker and apprehensive of him.

Costume
Everybody in the room first is dressed in posh suits and at first glance look like they are very hard working men who are in a conference. This is obviously not the case though and it uses the audience's feelings to manipulate the situation. This is because the audience will relate more to people who are dressed more casually than those who who are dressed smartly and like they have a lot of money. This helps the audience weary of them and not trust them.
