Honestly, this movie really pushes the limit as far as censors in those days are concerned. I get the whole common law solution they give to us at the beginning of the movie, but I am referring to the many blatant references to sex in the film.
Ex: Robert Montgomery undressing at the end of the film, and Carole Lombard saying "don't you dare"
or the bedroom scene when she smashes the champagne over his head (it's very obvious what he was planning)
or the mother saying over the phone "well don't ...." (it's very obvious she said "don't have sex with him unless he marries you first").
This is really explicit stuff for the early forties. Sex isn't just implied, it's all but said on screen. How did they ever do it?
