With the exception of Titanic and two Disney films, every single movie below is part of a franchise, making us believe that there were probably some studio execs at Paramount or 20th Century Fox trying to convince James Cameron that he should do a sequel (“Are we sure that Jack really dies? Can he come back as a ghost?”). Speaking of Cameron, directing the two biggest box-office hits of all time is quite a feat, one we’re sure hasn’t gone to his head. That they were so different—an historic romance drama and a sci-fi action/adventure—makes it all the more impressive. The Russo Brothers are the only other directors on this list with two entries, and both of those were established Marvel properties they were handed, though we do admire what they did with the Captain America movies.
