Odd that the only person in the cast that concerns me so far is the guy with the most experience. He's got decades on Levitt, Blunt, and Dano, but it always feels like a coin toss with Wills, with not particularly promising odds. However, he is ocassionally roused from his ""I'm old, rich, and don't give a fuck" stupor by the right kind of filmmaker and hopefully Johnson will be that guy.
What I'd really like to see is some aggressive marketing muscle behind whatever Looper ends up being, but despite the cast (which one would think puts the product at advantage for obvious reasons) I doubt that's going to happen.
