Idea for a movie
As above, so below. A mathematician is recruited to work on a project predicting the outcomes of chaotic systems. He realises that the project has already mostly succeeded. It is being run by a group who are aiming to control the future. To figure the small changes in the present that will lead to the future outcomes they want. One of the mathematician's colleagues has already figured out what this group want and is trying to stop them. The colleague reasons that the only way to prevent small changes is a big change: something with massive and inescapable consequences like an act of terrorism. Now the mathematician has to figure out how he is going to stop both his colleague and their shadowy employers and so save tomorrow.
