Suspense in Thrillers

Thriller movies rely on suspense in order to create an atmosphere that provokes the viewer into wanting to watch the rest of the movie whilst at the same time gives them an element of power as they know what some of the characters don't know on screen. This creates a will they/ wont they scenario of questions that revolves around the action on screen.

An Example of this is Alfred Hitchcock's "Rope"

In rope the story revolves around to men who have murdered someone in a test of intelligence to see whether or not they can get away with it . They store the body in a chest and cover it with a cloth. They then have a party in which they place decorations and food on the chest as they attempt to fool guests and get away with murder. The suspense lies with the audience in that we know that the body is in the chest but we then question whether or  not the men will be found out by any of the guests.
