Robert Douglas credited as playing...
Michael, Duke of Strelsau
- Michael, Duke of Strelsau: How badly did you wound him?
- Rupert of Hentzau: Not fatally, I'm afraid. But the cabin is very damp, your highness - he could easily develop pneumonia...
- Michael, Duke of Strelsau: And let the Englishman reign for the rest of his life? Could we ever expose him?
- Rupert of Hentzau: That hadn't occurred to me.
- Michael, Duke of Strelsau: But if the Englishman died first, and was buried in the cathedral as the King...
- Rupert of Hentzau: There are moments in your presence, your highness, when I feel myself an amateur.
- Rupert of Hentzau: Odd, a man not knowing his own brother. But I assure you, they're enough alike to be twins.
- Michael, Duke of Strelsau: You're trying to tell me the man I saw crowned is an impostor?
- Rupert of Hentzau: Not your type of fiction, I see, Your Highness. Too incredible. But still, these things do happen. I knew twin sisters once who - but that's another story.
- Antoinette de Mauban: You promised to make me your wife. I want to be your wife. I want to love you and make you happy. Once you are regent, they would never let you marry me. Michael, take the happiness we can have together. Leave the power to your brother.
- Michael, Duke of Strelsau: No!
- Michael, Duke of Strelsau: I've played second fiddle to that drunken sot for the last time. His mother was a princess and mine was not, so he lived in the royal palace, he dined with kings. Well, today the feast is set for Rudolf. But it's Michael who will sit in his place.
- Michael, Duke of Strelsau: It's the day, the hour, almost the moment.
- Rupert of Hentzau: History is born out of a bottle of wine.
