This particular movie operates off of the interesting premise that the vampire you see onscreen is actually a vampire. This vampire is constantly in need of food and with all the camera crew around he is practically in an all you can eat buffet. After he's tasted a few of them the director becomes irritated, delivering ultimatums to the vampire who is really in control of the whole situation. By negotiating they come to the conclusion that the vampire can devour the actress of his dreams after the filming is over. .
By doing this we are given an insightful view into the world of filmmakers. Their world is full of turmoil and constant drama. In fact, the director takes his position so seriously that he and his associates wear white lab coats while filming claiming that they are scientists of the moving picture. This may seem silly but it is actually quite true. While filming scenes we see and hear the director guiding his actors through trouble spots with helpful hints, almost holding their hands as they act. He offers reassuring statements when they do something correct and harsh quips if they portray the character wrong. During the estate deal he continues to tell his actor to look suspiciously at the vampire, at the same moment the vampire seems to lose interest in the paper and is scorned by his director. When you watch these scenes your mind drifts back to the original movie "Nosferatu", and you begin to wonder if this is how it really was. .
In "Nosferatu" method acting was employed by the vampire to achieve the desired effect. For those uneducated in the lingo of filmmaking method acting is a term used to describe actors who take on a role so seriously that they almost become the person they are imitating. For example, the actor portraying the vampire in the original may have slept in a coffin, or he may have become dormant during the day and active at night. In these instances art becomes life, and vise versa.
