Of the last five movies directed by Michael Bay, four of them have had the word "Transformers" in the title, including the upcoming "Transformers: Age of Extinction." Meanwhile, James Cameron is gearing up to direct three "Avatar" sequels in a row, Peter Jackson will soon release his sixth Middle Earth adventure, and Zack Snyder could be calling the shots on "Man of Steel" sequels and spin-offs for the next few years.
