My theory is this: regardless of the movie poster's imagery or logline, if I change nothing else but add Frankenstein to the title, it will radically change the viewing audience's concept of the movie.
Despite how contrary the rest of the imagery and wording may seem to FRANKENSTEIN, it will feed into the the viewer's altered perception of the movie instead of clash with it.
Even more, it will probably give the movie a better than fighting chance at the box office.
Today's example, GODARD MON AMOR.
