Writer-director Duncan Jones follows up his excellent Moon with this mind-bending thriller about a military man (Jake Gyllenhaal) sent back in time to prevent a terrorist attack. That’s the short way to describe it. Truth is the film is far more complicated and mysterious than that, featuring Gyllenhaal’s best work since Brokeback Mountain. Gyllenhaal’s character winds up on a train where he is forced to relive the same eight minutes over and over again in an effort to solve a bombing mystery. Michelle Monaghan is excellent as a wonderful woman who doesn’t know she is going to blow up. The film keeps you guessing and involved throughout its running time, which is more than I can say for most thrillers. Jones is officially right up there with the best of them when it comes to putting together great sci-fi films.
