The Fear Index

Dr. Alex Hoffman, an American ex-pat physicist, creates an AI-driven system that exploits fear in the financial markets and operates at lightning speed to make big returns. But on the day of launch, Alex’s sanity is shaken after he is viciously attacked at his home by a man who knows all of his security codes. After more unexplained occurrences, Alex becomes convinced he’s being framed.
It loses a bit of the impact and edge if you already know the book. But it's still a good adaptation. I think Hartnett played really well.
[spoiler] Harris picked up something here one should think about. It's not total science fiction. Yes, there is no true AI, yet. Beside that this is something I can see happening in the future. [/spoiler]
