NOT a 'Screwball Comedy'
I understand why this film is cited as being the origin of the popular "screwball comedies" of the 1930s.
HOWEVER, if you watch this movie and compare it to the later genuinely "screwball" comedies like "You Can't Take It With You" and "Bringing Up Baby", IHON does NOT have outrageous lunatic characters and rapid-fire dialogue like those later films.
One thing I always noticed about the "screwball comedies" is that the stars in them like Cary Gran and Katherine Hepburn KNOW they are in a wacko-fest, and therefore push their behavior accordingly: over-reacting, physically contorting and mugging for the camera.
In IHON, on the other hand, Gable and Colbert - most likely because both stars were not fond of the script and simply wanted to complete filming asap - play their parts very straightforwardly, without exaggeration.
THAT is one reason this movie works so brilliantly: the circumstances are pretty much over the top, but the characters are all believable and earnest in their performances.
Oh it's definitely a "comedy" - and the story is outrageous to a degree - but there are no "antics" or horseplay that mark the later "screwball comedies."
GREAT MOVIE!
