"long scene where she is trying to show off to her husband that she can smoke a cigar"
"It's a costume comedy, just after the Civil War, so Myrna Loy goes about in hoop skirts. In the scene, Myrna Loy is upset because her husband refuses to have his portrait painted. 'How would you feel if I behaved in an unconventional manner?' she asks. 'What would you do?' he asks. 'Oh, I don't know, go out without a hat or gloves. Or smoke cigars like that woman in Paris, Madame George Sand.' Her husband goes out, so she sends the maid out to buy a cigar. She takes it into the living room and fiddles with it. She tries to cut it with scissors, then does the old bite & spit. Then she sits down and strikes a few poses. (The scene is interrupted several times by reaction shots of the maid, who is hiding and watching.) When she hears the door open, she lights the cigar (without difficulty) and puffs casually as her husband walks in. He pretends not to notice the cigar, and introduces the ladies from the Puritan Society, who are horrified. Fade to black..."
