Character mistake: When Mr. Brooks and Marshall hack into the police database and are looking at detective Tracy Atwood's financial records there is a screenshot of the computer screen showing some very terrible spelling.
Continuity mistake: During the van chase sequence, the van door is open for the first few minutes. Then the van makes a sharp right turn and immediately it cuts to the door which is now closed. In the immediately following shot, it's back open yet again.
Mr. Smith: If you're planning on doing anything...
Mr. Brooks: We're both aware of the rules Mr. Smith, but I feel I must warn you that if you enjoy killing, it can become very addictive; it can ruin your life.
Trivia: At about 1.48, while Mr. Brooks is reading a paper in a diner, the newspaper - USA Today - has only the headlines and first few lines written in English. The rest is in Latin. You can see it on the Bluray disc.
Question: What type of personality disorder does Mr. Brook have, is compulsive killing part of it, and is it really genetic?
Chosen answer: It sounds like Dissociative Identity Disorder. And I think compulsive killing is something he chooses to do, and not connected to his DID; and from skimming the article, it doesn't appear to be genetic.
