Black Christmas (2006) Trailer that contains scenes that aren't in the movie.

The 2006 version of Black Christmas has a questionable production to itself. The trailer of the movie contains scenes that aren't in the finish movie because the studio went behind the director's back and made these scenes. Now the scenes are Melissa pointing a shotgun at the door, Billy is hiding from the main character on the ceiling, a unknown woman discovering a woman floating beneath a frozen lake, and a woman falling from the roof and getting dragged by a some shredding machine. These scenes are for promotional purposes.
