Great Moments In 20th Century Film

I was watching Viaggio In Italia, which is an Italian film from the 50s about an English couple on holiday in Naples. They realize, through little scenes and interactions, how little they really know each other. One night, after attending a party where the husband observes his wife laughing with other men, they return to their hotel room and say the following:

Husband: "Have a good time?"

Wife: "No."

Husband: "That's strange. Been a long time since I've seen you in such a good mood."

Wife: "Well, you seemed pretty gay yourself."

Classic Ingrid Bergman.
