I'd certainly like to see more female directors; here's a post on why female directors almost never get blockbuster gigs from Indiewire.
Here's a riddle for you: A director is casting his new blockbuster film for a major studio. His son, who is an actor, is up for the lead role as the plucky youngster who saves the world. The director worries it will look like nepotism to cast him, and so he doesn't. Later, the director is fired from the project. His replacement resumes looking through the casting footage, but when it comes to that same actor's audition, the new director exclaims: "I can't cast him, he's my son!" Can this be possible? Because you likely will have identified the above as a version of the old "no-one-believes-a-doctor-can-be-female" riddle, your answer should be that if the second director is a woman —that is, if she is the actor's mother— this scenario is entirely possible.
