If you loved Trouble in Paradise, try Design for Living
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Ernst Lubitsch, and they both carry the cozy, cult mood tags, and they sit in Comedy / Romance territory. If that's the register that drew you to Trouble in Paradise, the second film will land in a comparable space — through a different lens.

What Design for Living is
Here's a film unafraid to ask, "Can't we all just get along? And sleep together?" Gilda, a commercial artist, finds herself juggling the affections of two men, who decide to share her rather than lose her. It's all very European, though perhaps not as risqué as it thinks it is.
