Before watching the movie:
It seems like I’ve run into “dealing with unusual problems from an erroneous medical report” before, but I can’t recall where. Some sitcom episodes may be coming to mind, but I think I’ve seen movies based on the idea too.
I must have seen Carole Lombard in movies before, but apparently not in movies reviewed here as she doesn’t seem to have a preexisting tag. The same for Fredric March, though I have even less of an idea what to expect from him.
Anyway, the pair are tied together by a medical mistake. She was expected to be dying, and he was apparently somewhat responsible for the media coverage, and then she turns out to be healthy, and they have to… fix that. Somehow. By verbally sparring, apparently.
