Camera Angle/Shots for Film

Instead of using a tripod by using handheld the shot seems more realistic which also adds a sense of panic.
By zooming up onto the characters face you can see their emotion and how they are feeling at the present time.
Using low key lighening it adds an effect of darkness. Focussing on one thing can also add awareness and focusses on one thing at a time giving an edgy feel.

Tracking and Pan shots are commonly used in the beginning of thriller films, particularly a certain group of people who we should be interested in as the audience.

Jumps cuts are also common as they allow us as the audience to make assumptions on what the story or characters will be like.
