One of the reasons why I absolutely love Christopher Nolan, he is absolutely unlike many other film makers easily swayed by the dollar sign. Every movie he made so far were pretty much "stand-alone" kind of movies, the kind that doesn't really sets itself up for a sequel.
However, some might argue that the last Batman movie did end with quite a bit of a cliffhanger. Although I personally think it was simply as a mean to complete the character arc for Bruce Wayne/Batman. Still, it did leave everyone with an anticipation for more, and so Christopher Nolan confirmed that he will make one final Batman movie entitled, The Dark Knight Rises.
