That Uncertain Feeling is an absolute gem. The film is incredibly well-focused, and unlike
Cluny Brown or some of his other films, the plot kicks in pretty immediately, with a wife bored from an inattentive husband, and her falling for someone else. Melvyn Douglass is spectacular as usual, but really puts in an amazing performance here. His tone shifts from aloof to arrogant to deranged and carefree, and he pulls it off marvelously. One moment he's weeping as he's unable to part in his marriage, and the next he's pulling off hijinx in order to win her back. There are lots of touches of real black comedy here, including an absolute gasp-worthy moment
when Douglas does a sarcastic Heil Hitler, which comes out of nowhere, but I found it even more shocking and showstopping than the famous line about Shakesepeare and Warsaw (I think?) in To Be Or Not To Be.
Superb film, which is probably the driest comedy I've ever seen from Lubitsch.
I also caught
Trouble In Paradise the other day. I've nothing exceptional to add that I'm sure isn't obvious to its films admirers. For whatever reason, the first time I saw the film on DVD it did nothing for me (which was unusual for a Lubitsch film). In a theater it all came alive, however. Lubitsch's jokes are never obvious or expected, but they are exactly what they should be (the pickpocketing of the main couple for example). Probably not my favorite of his films, but clearly in the running for one of his best.
