Anderson had every move scripted before the shoot even began.

One of the things that is regularly said about Anderson is that he has great persuasive powers and picks his collaborators with great skill. He wrote The Royal Tenenbaums specifically for the notoriously private Gene Hackman. Hackman at first found the script too detached: "I am generally better at emotion," he said later. And too specific: he didn't like the fact that Anderson had every move scripted before the shoot even began. He was persuaded when Anderson convinced him that he would not make the movie without him. "I've seen it already in my head." (Guardian)
