Normally, the movie trailer will not be made by the director (even the director does not do even the opening), but the splendid trailer of that "Gone Girl" was what David Fincher himself did.

Moreover, although this stunning trailer is developed together with famous piece "SHE", in the movie "Gone Girl" main part, "SHE" is a fact that it is not actually used at all. If you look at this, you will want to see the movie again.
