Underworld 2: In a recent interview with MovieHole, Underworld director, Len Wiseman, spoke about what to expect from his Vampire/Werewolf sequel:

"This time we can expect more history about the vampires and the werewolves, which we weren't able to do in the first one. There's going to be a bit of actual battle in the medieval times between the werewolves and vampires, with like army-clad vampires on horses, kinda like "Braveheart". It'll play out a bit like "Indiana Jones and the Last Crusade" where the first ten to fifteen minutes of the film will be a prequel. We're going to really dive into the dark ages, and then centre some more on the modern day. We will have a lot of the same cast, but also new cast too. It's in early development, so of course we have no idea whom, but yeah, some new people will be involved
