Source Code

Colter Stevens (Jake Gyllenhaal) is a military pilot serving in Afghanistan who finds himself unexplainably on a train to Chicago with an unknown commuter companion (Michelle Monaghan) who obviously believes him to be someone else. Eight minutes later the train is destroyed in a bomb blast.

As the dust from the blast settles dazed Stevens finds himself under the control of Goodwin, a military woman (Vera Farmiga), directing him from a computer screen under some form of experimental process named 'Source Code' which enables him to live the final eight minutes of a dead person's life.

Stevens is sent back to relive those final eight minutes over and over with the aim of identifying the bomber who it is believed will strike again.

This is a quite slickly enacted and mostly superior science fiction. The film maintains a reasonable degee of mystery whilst the identity of the bomber remains undetermined. Once the bomber is identified the film falls away slightly and the concluding scenes left me a bit befuddled.

Overall, pretty good value for science fiction lovers.
