Moon director Duncan Jones has offered up some casting information for his newest film Source Code. Here's what he had to say via his Twitter account:

Just met with the lovely Vera Farmiga (The Departed) and Jeffrey Wright (Quantum of Solace). Feeling quite thrilled to have two such scorchingly good actors in Source Code!

Source Code centers on 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 harrowing train bombing until he can find out who is responsible for it.

Farmiga will play a hands-on communications officer controlling Gyllenhaal as he travels through time and space. Monaghan is a woman on the train with whom the man is involved romantically.
