"Source Code" opens with confusion: Capt. Colter Stevens (Jake Gyllenhaal) wakes up, face pressed against the window of a commuter train. He doesn't know where he is, or how he got there. When he looks in the bathroom mirror, the face he sees is not his own. Yet no one else seems to think anything is amiss. Indeed, Christina (Michelle Monaghan), the attractive woman sitting across from him, appears to be in the middle of a perfectly normal conversation with him.
Director Duncan Jones premiered his thriller Source Code at South by Southwest on Friday, bringing a tech-savvy movie to a high-tech festival.
