In "That Uncertain Feeling", good performances by the three lead actors give some life to a rather simplistic story. It is a mildly amusing movie, but there isn't enough to the plot or the script to make it any more than that.
Melvyn Douglas and Merle Oberon play a married couple who seem to be reasonably content, but a chance meeting between the wife and an eccentric pianist (Burgess Meredith) suddenly threatens their whole marriage. Rather than choosing direct confrontation, the husband tries to use psychology to turn the situation in his favor, leading to some comic situations that only partially come off.
The three leads are all pretty good, especially Meredith, who has the liveliest role. And Ernst Lubitsch directs with his usual dapper style. But there isn't really much of a story, and the behavior of the characters, while generally humorous, is too often completely implausible. So the movie is really never more than mildly entertaining.
This will probably only be of particular interest to those who are fans of the director or one of the stars.
