Watch the first minutes of this movie and you might think you’re watching the wrong version because it starts with French dialogues. Of course that happens all the time in French movies but seldom in US American like the one we’re looking for today.
Like many films it’s based on a play but it’s said to retain only a single line of the original play. Oh, and it’s a pre-Code talkie so there are some things in there one couldn’t see/hear the next twenty years after its release in US pictures.

If you want to have a romantic dinner at home then send your butler to bed to be alone with your guest. That is, of course, if you have enough money to afford a butler. Just send him to bed with the words go to bed, little father. Then have a little chitchat and wait for the clock to strike twelve.

Then go ahead with this dialogue (only works if you’re in Paris though):

“Do you hear that?”
“It’s twelve o’clock.”
“It’s midnight. Look at the clock. One hand has met the other hand. They kiss. Isn’t that wonderful?”
“That’s the way a clock works. What’s wonderful about it?”
“It’s midnight. One half of Paris is making love to the other half.”
“You merely feel you must put yourself in a romantic mood to add to your exhilaration.”
“I can’t possibly think of any better reason.”
“That’s false sentimentality.”

So, from which movie is this very romantic extract?
