- Mrs. de Winter: Our marriage is a success, isn't it? A great success? We're happy, aren't we? Terribly happy? If you don't think we are happy, it would be much better if you didn't pretend. I'll go away.
- "Maxim" de Winter: How can I answer you when I don't know the answer myself? If you say we're happy, let's leave it at that.
Joan Fontaine - Mrs. de Winter
Laurence Olivier - "Maxim" de Winter

Alan Mowbray - Dr. Vengard
