Source Code, a science fiction movie from Duncan Jones—who previously directed Moon—features Jake Gyllenhaal, Michelle Monaghan, and Vera Farmiga in the main parts, along with a cameo by Russell Peters. Where Moon was more deliberate, Source Code moves at a quicker pace as an action-oriented story. The narrative centers on a character who is sent back through brief, recurring eight-minute periods to find out who caused an explosion on a train. As these sequences repeat, the storyline becomes increasingly complex. It's a solid film that holds your attention and gradually unveils its secrets. The actors deliver strong performances in their respective roles. This science fiction offering is worth seeing at least once, though watching it again might help you fully understand everything.
