I think it is the easiest mentality for a human being to be either colonized or to colonize. The structure of either the slave or the master seems to be the simplest and the most relaxing one to slip into. Either you are a slave, and you don't have to think for yourself, or you're a master, and you don't have to work for yourself.
I would say that a lot of the characters I've been attracted to are very vulnerable and they expose themselves emotionally. Not so much in 'The Fighter,' not so much in 'The Master' - I think those are different.
America Online, of course, is a master of the hard sell, from stuffing mailboxes with free trial offers to forcing subscribers to click through ads before they can get their e-mail.
My way of getting the best from people on a set is to notice their work, to make every prop master, every seamstress, part of 'The Newsroom' or 'The West Wing' or 'Steve Jobs.'
