How is suspense created in collateral?

Collateral is a thriller directed by Micheal Man in September 2004. The film is about a cab driver called Max, who finds himself being the hostage of an engaging contract killer Vincent, as he makes his rounds from hit to hit during a night in LA. Max must find a way to save both himself and one last victim, Annie.

There was many suspenseful moments that were created during the film. An example of this is when Max crashed the car. The music gradually got louder when this was happening but suddenly stopped when the car had come to a halt in the middle of the road. this creates a lot of suspense because the audience can't guess what will happen next or even if the characters are still alive.

Another example of suspense being created was when Vincent was at Annie's workplace. However, Max was opposite the building on the top of a car park. The suspense was beginning to gradually increase because the audience was allowed to see that Max could see into the building to where Vincent and Annie are. The music was gradually brought in and slowly gets faster. Vincent decides to cut the electricity off in the building. When this happens the music suddenly stops and we cut to a close up of Annie's face being shown with fear. This has built up a lot of suspension as the audience want to know what happens to Annie. 

Another example of how suspense has been created, was when Max and Vincent were on the train following the incident in Annie's workplace. Max and Vincent are on opposite sides of the train doors. This has already began to build up the suspense because they are both pointing guns at each other. Soon into the shooting scene Vincent realises he has ran out of bullets. At the same time the music suddenly stops, however, this could represent what will happen next to Vincent. This has created a lot of suspense because the audience want to know what will happen to Vincent - will he live or die?
