Source Code

When decorated soldier Captain Colter Stevens wakes up in the body of an unknown man, he discovers he's part of a mission to find the bomber of a Chicago commuter train.

Source Code landed as one of the smarter sci-fi thrillers of its moment, with Duncan Jones drawing frequent comparisons to Groundhog Day while critics argued the film deserved to be judged on its own terms. The script's fractured, loop-driven structure drew the most attention — reviewers debated whether the high-concept mechanics overwhelmed the human story or actually deepened it, though Gyllenhaal's performance and Ben Ripley's screenplay earned broad respect even from those with reservations.
