They are doing a third "Underworld" movie. But this one has no Kate Beckinsale and her husband/director Len Wiseman is not directing. This type of change normally spells doom for a movie franchise. It's going to be especially hard to see without Kate back as Selene. Rhona Mitra is now in the lead as new character Sonja. I really enjoyed the first two movies and will probably see this one when it comes out in Jan., 2009. Here's a picture of Rhona from the movie below and a link to a couple more.

I've been following this for a while. This is the prequel to the story and is more about the werewolves rebeling. I think Sonja is the dead daughter.
New full trailer! Looks very cool!
