I've read a lot about Norma and she was extremely vain and body-conscious, so I am surprised she allowed herself to be photographed in that riding outfit, as she was especially concerned with her legs. She maintained a vigorous exercise schedule which was unusual for her day, when most of the actresses went in for massages, which was somehow considered the equivalent at the time.
The movie has more of a theme and plot than, say "The Divorcée", as it involves a dramatic legal case, pitting her alcoholic father against her racy new lover, played by Clark. Norma's character is forced to agree not to see him anymore if her father will quit drinking forever. But she doesn't have to give him up for long...and Norma's reaction to seeing him drunk again is startlingly overacted, but kind of funny to see.
Overall it is not a bad film; as much as I love watching the movies from the thirties and forties, some of the sets look so patently false, it is kind of jarring at times. And it is always fun to see Clark Gable charging around a screen.
