Oscar Isaac... with Cat

If Jonesy starts hissing, Oscar, run! He's spotted an acid-blooded alien or at least a Hyperdyne Systems 120-A/2.
Actually Oscar is just hauling around a new co-star (role size to be determined) on the set of Inside Llewyn Davis in which he plays Llewyn Davis, a singer songwriter in 1960s New York. The best part of this news is that this is the latest from the Coen Bros and it's filming already. Inside Llewyn Davis reunites Oscar with his Drive wife Carey Mulligan who is contractually obligated to be in every picture released for the next four years. Other costars include Garret Hedlund, Justin Timberlake (now no longer a musician at all though maybe someone should tell him he's more fun as a pop star than as an actor? SNL hosting aside), Stark Sands, F Murray Abraham and Coen Bros mainstay John Goodman.
You only have to wait until 2013 to see it.
