A hilarious thing about the movie business is that you can get away with anything as long as you call it "process." Literally, anything. I mean, he's sound asleep! The director is literally sound asleep on set - what the hell's going on here? Well, he's slept through his last three movies, and they were huge hits. It's how he works; that's his "process." He'll wake up at some point and give notes, but for now, let him catch a few Zs. I haven't been in the business that long, but at this point I can't think of a single outrageous behavior that I haven't seen occur on set and then heard excused as someone's process.
