Consider the perverse effect cap and trade has on altruistic actions. Say you decide to buy a small high-efficiency car. That reduces your emissions but not your country's. Instead it allows somebody else to buy a bigger S.U.V. - because the total emissions are set by the cap.
I have done many movies that people hadn't seen. 'The Fountain ' I spent a year on that. 'The Prestige' with Chris Nolan and 'Australia.' From my perspective it's very satisfying. Some movies people see and other movies they don't. 'Wolverine ' 'X Men ' I know that in some level people know me just for that and it's fine for me.
