That Uncertain Feeling is a gem of a movie, but you won't want to buy this version. The picture quality isn't good -- too fuzzy. But worse yet, the manufacturer Real Enterprises superimposed a "R E" logo onto the lower right corner of every frame of the movie. This is simply unacceptable for a commercial DVD. I returned my copy to Amazon.
I see now that on a well-known auction website they're selling a much newer release of this movie under the "American Pop Classics" label. Perhaps it's a better print -- they claim it's newly restored. I haven't seen it.
The movie itself, a gentle satire of the foibles of the upper middle class in the 1930s, is wonderful, with subtle, sophisticated wit in every line, and every actor perfectly in tune with Lubitsch's vision. I think it's some of Lubitsch's best work.
