I am Legend shows that the hunter can also be hunted. In scene 6 director Francis Lawrence uses a infected dogs come out a night poster hung on a cabinet as a motif that you will see the relevance of that poster later on in the movie as Dr. Nevell's dog is attacked by one of those infected dogs which eventually is put to sleep.
In Scene 14 Francis Lwarence use low-key lighting when the Darkseekers have trap Dr. Nevell and are waiting for the sun to set. In this scene the windows in the building are black, the water that Dr. Nevell stepped in to spring the trap is extremely black. In the long-shot as Dr. Nevell is attempting to get back in his truck the scene is a grayish color giving you the feeling that he is not going to make it to his truck before the Darkseekrs get to him.
Im a Legend shows that the Predator can be prey when given the opportunity
