You really haven't seen any misleading movie trailers? That's surprising to me
. The worst example I can think of is "Drive", where a lawsuit was actually filed by some crazy woman because the trailer promised an action-packed film and what she saw instead was...well...the movie "Drive". Misleading trailers are pretty common. Paranormal Activity 3's trailer was comprised almost exclusively of footage that was not included in the film's final cut.
But anyway, it still doesn't matter to Marketing. The difference between this and Werewolf is that Werewolf is an old movie...they didnt have to sell the movie to the fans, but instead vice-versa (because it's old and because since there was no opportunity for synergy, the success of the house was based entirely on its own merits). Thats not the case with Dracula. It's primary purpose is to generate interest in the film. If it did that based on what was in the house, then it's successful.
