This question already has an answer here:
What was the first known instance of a story that provides a relationship between werewolves and vampires? What was that relationship?
In some movies (Underwold, Van Helsing and Twilight), werewolves are portrayed as the vampires' slaves: as the latter represented the aristocratic class, who were on the top food chain thanks to their human-like appearance and self-control. Totally the opposite for the werewolves, who were simply seen like savage beasts, who cannot control themselves (Twilight, Underworld).
