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.
Mr. Brooks (2007)
1 character mistake
Directed by: Bruce A. Evans
Starring: Kevin Costner, William Hurt, Demi Moore, Dane Cook, Marg Helgenberger
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.
Answer: Marshall's line was, "Why do you fight it so hard, Earl?" Earl Brook's was, "God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference. Living one day at a time and enjoying one moment at a time, accepting hardships as the pathway to peace. Taking, as He did, this sinful world as it is and not as I would have it, trusting that He will make all things right if I surrender to His will, that I may be reasonably happy in this life, and supremely happy with Him forever in the next. Amen."
