A fast-paced action thriller carried by the acting chops of Jake Gyllenhaal and Michelle Monaghan. A military captain is given the ability to relive the same 8-minute cycle of time, to try and solve the mystery of an initial terrorist attack - somebody blows up the CCR Chicago commuter train he is put riding. This movie was fun with it's pace and execution, and it was engaging with all of the multiple revisits and versions of the same scenarios playing out. You will pick up clues and try to identify details as each version of the train explosion plays out - along with our main protagonist. A nice, taught thriller with perhaps one too many source code occurrences.
