To this point, the only person tapped to star in Source Code, the next scheduled project for Moon director Duncan Jones (Moon, on DVD and Blu-ray now) is Jake Gyllenhaal. That is, until today…

Heat Vision is reporting that Golden Globe nominee Vera Farmiga (Up in the Air) and Michelle Monaghan (Trucker, Eagle Eye) are both in talks to star alongside Gyllenhaal in the time-travel thriller. The reported story follows a soldier (Gyllenhaal) who, as part of an experimental government program to investigate a terrorist incident, finds himself in the body of an unknown commuter living and reliving a train bombing until he can find out who is responsible for it. It’s like Groundhog Day, but more sciency and terroristy, and less funny.

Farmiga is in talks to play a hands-on communications officer controlling the soldier as he travels through time and space. Monaghan would play a woman on the train with whom he has a romantic relationship.

This adds a lot of firepower to the sophomore effort of Jones, who is still making waves with the oft-overlooked Moon. The premise of the movie is one that seems in his wheelhouse, and the cast he’s assembling is a talented one. I see no reason for anything but optimism here.
