He didn't direct the first Babe, he just wrote the screenplay. He directed the sequel, pig in the city

oh there's multiple babes? Damnit

Yup and the second one is much more surrealist, and again Miller directed it. But of course you can say he made both movies as he did write and produce the original Babe film, he just didn't direct it. Honestly the more fact is he wrote, directed and produced both Happy Feet movies.
