Movies assisting the Script

While I was writing the script for our preliminary video, a few movies helped me out in designing the character of the psychopath. These include 'Fight Club', 'Se7en' and 'Silence of the Lambs'. Each of these movies features a different kind of psychopath with different level of mental illness. Yet, each character also portrays common attributes such as they are all calm in normal conditions and do not reveal that they suffer from some mental disorder.They do everything for a reason or appear to be able to explain all their actions through logic,and they usually speak softly. But once they are provoked or are bringing out the violence hidden in them, they prove to be very wild and hyper active.
For example, in 'Se7en', the psychopath(John Doe) murders people who have committed one of the 'Seven Sins'. He brutally murders the victims but later he gets himself arrested as he walks into police station covered with blood. He then appears to be calm and composed during the rest of his scenes. He acts as if he is innocent and tries to justify his actions by claiming that whatever he did was for a good cause.
In 'Silence of the Lambs', one of the psychopaths shown in the movie(Dr. Hannibal Lecter) assists an FBI detective in solving a case. He is a prisoner held in a psychopathic ward and he himself was once a Psychiatrist. He is also shown speaking calmly most of the time and has powerful dialogues that not only help the detective with the case but help her with her personal problems as well, In fact, she is some what influenced by his character. Yet he resorts to brutal violence in some scenes.
Keeping in mind these aspects of a psychopath, I added more detail to the background of my character and rephrased my script in such a manner that my character also behaves and speaks in a similar way. This also helped me to create some suspense in the scene.
