Shadow of a Doubt, Young Charlie realizes that Uncle Charlie is a killer from what source?

The more flaws and insecurities a villain has, more the spectator will recognize his humanity and, as humans themselves, be aware of how malevolent he can be. He believed that his antagonists should be attractive and complex in order to awaken curiosity. This can work very well in some horror movies, but fails to arouse the psychological tension Hitchcock was looking for. If the character of the villain is plain, the audience first reaction will be to repel him. François Truffaut said that “the better the villain, the better the picture”, and a careful analysis of Hitchcock’s movies can confirm this statement. The effectiveness of suspense relies on uncountable elements, however one figure is the basis upon which this kind of plot stands: the villain. His films never get old and are not only meticulously shot, but also filled with thriller, humour and fascinating characters. With an astonishing filmography of more than fifty movies – from primordial silent black and white to colored ones –, he has become a reference on both technique and narrative. Alfred Hitchcock is known worldwide as the Master of Suspense, and it is probably an unanimity that this title should not belong to anybody else.
