Peter Sciretta from /Film has compiled a list of the ten highest revenue generating Hollywood film directors. Obviously, Steven Spielberg tops the list and, if you want a list of the next ten, check the comments.
Interestingly, as Sciretta points out, six of the top ten have been involved in trilogies, three others have been involved in big franchises, and the only one who hasn't done either is in the process of directing his first sequel. Oh, and they're all white men, of course.
