Let Us Be Gay is a 1930 American pre-Code romantic comedy-drama film produced and distributed by MGM.
It was based on and filmed concurrently with the 1929 play by Rachel Crothers which starred Tallulah Bankhead and ran for 128 performances at London's Lyric Theater.
Housewife Kitty Brown (Norma Shearer) does not spend much time on her personal appearance.
Bob is embarrassed to be seen with his wife because he considers her dowdy and he does not like the homemade clothes she wears.
Kitty gets a shock when Bob's latest girlfriend, Helen, shows up at their home.
Diane's grandmother, Mrs. Bouccicault (Marie Dressler), is a leader in local society and disapproves of the match.
The other weekend guests, including Townley (Gilbert Emery), Madge (Hedda Hopper), and Wallace (Tyrell Davis), are baffled by the way Bob and Kitty behave around each other.
A few minutes later Mrs. Bouccicault comes to Kitty's room to announce that Bob has just become engaged to Diane.
The next day, Bob is upset to overhear Kitty making plans for a yachting trip with Townley.
