There are several moments in White Dog (White Dog, 1982) show that the genius of Samuel Fuller.Two in particular I would highlight here.

The racist dog is loose on the streets. A black boy out to play on the sidewalk. Just when the dog would see it and may cause another tragedy, the child's mother pulls her inside. The dog follows his way peacefully.

Another photo is not available in the google, but it is spectacular. The owner of the dog will find a wayto make the animal loses the will to attack people. She talks to Carruthers, friendly old man who explains, eyes full of tears do not flow, a dog trained to attack is very difficult to be untrained. What was to be sacrificed. She is leaving the establishment, when the camera moves down, revealing a plaque with the inscription: Carruthers and Keys - animal training. It closes in KEYS to focus immediately afterthe partner that bears that name, whose black man entered the scene indicates his heroism.

Sounds simple, but it's the kind of thing that nobody else does today. The camera movement indicatingthe only way out. Soon after, the Keys are beautiful eyes beautiful eyes of the dog, and man decides to accept the mission almost impossible.
