Julia Jones may not be in the twilight of her career yet but this natural beauty from Beantown will showcase her talents in two back-to-back movies this summer, Jonah Hex as a busty prostitute named Cassie and The Twilight Saga: Eclipse as she-wolf Leah Clearwater. Not bad for a former model turned actress, who was last seen in the Tarantino flophouse Hell Ride.A word from Julia: "If you try to scowl, just for four hours straight, you will start feeling pretty pissed off. I'm not kidding."Yeah because you're scowling for four hours straight. If I'm doing anything for four hours straight I'd get pissed off. Yes, even eating nachos.More pics of Julia smiling after the jump.
