HA! I knew it...another movie based on a Philip Dick novel. (fate vs free will, Damon character apparently discovers secret "doers" behind the scenes of ordinary life, adjusting fate here and there).
Reminds me of a Twilight Zone about the "Blue people" (workers in the Twilight Zone dimension working feverishly to engineer events before they occur in our (3-dimensional + time) world. Main character somehow sees some of the Blue People. Can't remember the ending. http://www.imdb.com/title/tt1385826/
