Two Things
One: Could this film's opening have been an inspiration for the syncopated-sound-effects opening of Delicatessen?
The other: I happened to catch The Smiling Lieutenant not long before re-seeing Love Me Tonight. The former, of course, is Lubitsch, but in it Chavalier's way way way more credible a leading man. He's fallible, likeable. Even when he sings, he's not the mimicry of himself that he seems here. How sad to see him turning into what Pepe le Pew justly parodied.
