A scene from “Unfinished Business”

Prince Philip: I can be a tough old nut, but I've always had a soft spot for you. Maybe because you're young. Maybe because you're a beautiful woman. Maybe because I often share your frustration with your husband. I've always felt protective of you. Fond of you. There, I've said it. So when I see you making errors of judgment, I want to lean across the table and remind you, I'm on your team. What am I trying to say? You're not a novice anymore. You're long past the point of thinking of us as a family. That's the mistake people make in the beginning, but you understand, I think, it's a system. And we're all in this system. You, me, the Boss. The cousins, the uncles, the aunts, the lepers. For better or for worse, we're all stuck in it. And we can't just air our grievances and throw bombs in the air as in a normal family, or we end up damaging something much bigger and something much more important. The system. So the tip I want to give you is this. I mean, just, just be creative. You can break as many rules as you like. You can do whatever you want. You can make whatever arrangements you need to find your own happiness. As long as you remember the one condition, the one rule. You remain loyal to your husband and loyal to this family in public.

Princess Diana: You mean silent?

Prince Philip: Yes. Don't rock the boat.
