Ironically, Marian Seldes who plays "Nanna," Mona's mother, is actually almost two months younger than Katherine Helmond.
Mona: She makes me nervous and awkward and uptight. When she's around I feel like Angela.
Nanna: This isn't Jonathan, is it? How long has it been?
Jonathan: Eight birthday checks. And thanks for keeping pace with inflation.
Mona: I just want to get you some tea. Tony, where do you keep the water?
Nanna: All boobs, no brains. I say that with love.
Tony: After I'm finished turning on the old charm, I'll have her eating out of my hand.
Mona: All the way up to the elbow.
Mona: So, have you got her eating out of your hand yet?
Tony: No, but she showed me a lot of teeth.
Tony: I don't care. If I can't win your approval that's okay because I can give Angela something better than money, and class and a great life. Eww.
Nanna: Painted ourselves into a corner haven't we?
Nanna: When I told her that I was going to give you the candlesticks, I mentioned that I was concerned they stay in the family.
Angela: Why wouldn't they?
Tony: Yeah, stuff like this is kinda hard to pawn, you know?
Paul: As your lawyer, it's my duty to inform you that once you're married, you may have a real interest in this house.
Tony: You mean aside from cleaning it?
Paul: By taking care of the home and allowing Angela to do her job, the law credits you with producing half the assets of her business.
Tony: No wonder I'm so tired at the end of the day.
Nanna: Don't say something you're going to regret.
Mona: Daddy faked his death to get away from you!
Mona: He was a beautiful young man; kind and considerate, and so talented. And if it wasn't for her, today I would be Mrs. James Earl Jones.
Mona: We met when he came to down doing Summer Stock, but Mummy didn't approve of him.
Angela: Because he was black?
Mona: No. Because he was an actor.
Tony and Angela: Ohhh.
