Co-writer and director Len Wiseman couldn't be happier with "Underworld": Being a horror/sci-fi fan himself, he got to choose this film as his first film directorial project, he met his beautiful fiance (Kate Beckinsale) while shooting the movie, and now the movie's doing well enough for Sony/Screen Gems to greenlight a sequel.

So what will the film be about? Wiseman revealed to Cinema Confidential a couple of weeks back that there are prequel/sequel possibilities, and maybe a combination of both. "There’s actually a sequel and a prequel that was mapped out when we sold this film. [Co-writer] Danny McBride and myself – there was so much that we wanted to tell in this story that it was getting a bit confusing for us to map out all the history and the wars. We said, 'You know what? Let’s map out a long story that would maybe span out three films and let’s then be able to tell our film in the middle.' But we had to kind of map out the whole thing to get to the point where we are now because it does have a lot of layers in it. But we do want to tell a lot of that back story and I’m obsessed with going back to the Dark Ages and showing the war when it was legions of werewolves fighting an army of vampires on horseback, invading their castle. I think that would be insane visuals! So that’s a bit of what the sequel is. We are already in the deal for the sequel and the studio’s incredibly excited about it. I think the 15 minutes [of the sequel] will be a prequel for the sequel, much like an 'Indiana Jones & the Last Crusade' type of situation."

Wiseman also revealed that the two leads, Kate and Scott Speedman, are interested in returning as well. "We all had a really good time, the actors and myself, that Kate and Scott are all for it."

Wiseman also revealed that he would like to see extensions of the story when I asked him about comic book spin-offs. "There’s a comic book now. It’s so strange for me because I’ve been a fan of these kinds of films and now that I can make one and all of a sudden, there are comic books, novels, action figures, Halloween masks, and the whole bit. They are taking this thing as a potential franchise and the comic book of the film has been made. I would like to see them develop a comic book that goes back to the Dark Ages and do a Dark Ages series. I think that would be really cool. "
