Casey Affleck is rumored to be re-teaming with director Andrew Dominik (The Assassination of Jesse James by the Coward Robert Ford), and gave some info during an interview with The Kevin and Josh Movie Show on Washington DC's CBS Radio:

I don't know if I'm allowed to talk about it, but it's a Boston-based crime... It's based on a novel set in Boston, but it's not going to be set in Boston, unfortunately.

No word on what the project is titled, although there is speculation that perhaps Blonde, the Marilyn Monroe biopic that Andrew Dominik is supposed to direct in January, starring Naomi Watts, might be taking a back-seat to this new project.
