East of Shanghai (1931)

When the young couple visits the Folies Bergere and a topless showgirl moves center stage, the wife remarks to her husband that the curtain came up too early since the girls weren't dressed yet. This film has previously only been available in edited form with very poor resolution; now that Kino Lorber has a restored blu-ray available, yes, there is a topless dancer visible for a couple of seconds.

A Couple cheats on each other while on a ship, a reference to meeting up for a fling in a cabin.

A couple of "damn"s and "hell"s.

Social drinking and smoking, as was typical in the '30s.
