Directors who cast their own kids in their movies
There's no business like show business — and show business is very often a family business. Watching the credits of our favorite movies can occasionally feel like skimming a family tree at the beginning of a historical novel with tons of powerful dynasties and relationships connected in some byzantine way. It isn't some sort of conspiracy, though: Plenty of powerful people in any industry try to help their children get their feet wet in the family trade, and if your mother or father happens to be a high-powered director, then the chances of getting a head start in Hollywood are a lot better.
These directors all understood the advantages of having some homebrewed momentum on your side in the acting business — and to prove it, they all cast their own children in their movies.
