I think you've got to talk to the director, see the director's films and recognise that it's important that the work fits right in and see if as part of the movie. ↗
I think soon after I became director of the CIA - President Obama pulled me into the Oval Office and said: 'Look, I just want you to know that your top priority is to go after Osama bin Laden.' ↗
Every time you say yes to a film there's a certain percentage of your yes that has to do with the director, a certain percentage to do with the story, a certain percentage with the character, the location, etc. ↗
