Film: You know how “director’s cuts” always come out some time after a movie comes out? Whose “cut” makes the theater?

There’s usually constraints put on the first release…stipulations the studio demands the director to stick with. As a result, many hours of film are never used. The directors cut is generally released for films that did well enough, and include deleted scenes that tend to make more sense of certain scenes and sometimes even the movie as a whole.
