Una Merkel steals the movie
I loved Una in every scene she's in. Her performance, in which she behaves like a genuine human being, is quite a contrast with that of Carole Lombard, who is quite manic throughout, playing one of her patented only-in-a-screwball-comedy movie characters. Even in simple little actions, like her annoyance at John Barrymore every time he entered her row in the courtroom, Una's facial expressions and gestures are priceless. I'd really love to see Una in more leading roles, but I'm not sure she did many. I've seen 17 of her movies, in all of which she had supporting roles.
Carole is quite watchable here, but I never quite believed her. And I wonder if that's a problem I have with some of her other movies, e.g. NOTHING SACRED and TWENTIETH CENTURY. Always fun to watch and listen to, but never actually resembling a real human being. I think it worked in MY MAN GODFREY because it was such an absurd situation, but I'd have to see that film again to be sure. I seem to remember her being excellent in TO BE OR NOT TO BE, but that may have been due to Lubitsch's handling of her. I may need to see more of her dramas.
