Stage Door, based on a play co-written by Edna Ferber, where the women are wonderfully funny.
(Betsy later went on to edit a book of funny writing by women, Funny Girl. Check it out!)
Even in comedies, when written by men, the women are often the butt of jokes, or impassively reacting to the humor, or sticks in the mud trying to shut down the comedy. If they’re allowed to joke, some male writers seem to fear they’ll take some of the agency away from the hero.
Exceptions are always refreshing. I recently read an excellent YA book written by a man in which the heroine has body-image issues, which is typical for the genre, and true enough to real life, but she’s funny about them, which is also true to real life, but something you rarely see in books written by men.
Yes, people have issues, and those issues can sometimes be serious, but don’t think that you have to be humorless to be serious. First and foremost, you have to convince us of the reality of the situation, and in real life, people have senses of humor about their problems, even if it turns out to be a grave situation. Stage Door has a lot of seriousness to it but the female characters are believable, which means that they have senses of humor. along with their more serious reactions.
