Suspense (a vital aspect in any thriller) is created in the build up to a climatic event; tension and uncertainty give the viewer an apprehensive and anxious feeling that breeds excitement and can make for an enjoyable film experience, keeping the viewer engaged. A common technique used to create suspense in thriller movies is a "forced plateau", this is the film equivalent of "foreshadowing" in a book, It's an ominous image that suggests that a huge event is about to take place.
Screen captures from the opening of Deja vu
Amidst all the laughter and a joyous occasion a little girl drops her doll in the water and the camera lingers on this disturbing picture. It is a hint of what's to come and an excellent example of a forced plateau.
