MTV got to visit the set of the "Underworld" sequel up in Canada not too long ago and revealed some interesting spoilers on what we get to see this time around of the vampire/lycan warring universe.

At the end of the original film, the sleeping vampire Marcus awakes and we get to see him in this, played by actor Tony Curran. "Marcus is the big ... yeah. You get to see what the relationship between [first-film villain] Viktor (Bill Nighy) and Marcus (Tony Curran) is, and what had gone on between them before we kick into the modern times of seeing Marcus again" says Director Len Wiseman.

Most of "Evolution" is set in the present day, but the film will flash back to two important moments in the timeline: one, a medieval sequence, explains the relationship between the main baddies; the other reenacts the first-bite story that Selene recounted in the first film. "It's like the first 10 to 15 minutes of the movie. We've got quite a bit of going back and history with Selene as well as Viktor, Amelia (Zita Görög), the elders, and Marcus as well and seeing where he fits into the whole story. That's what the medieval sequence is all about" the director continued.

Another new aspect is the 'Cleaners'. This group of mysterious characters show up after each battle and assure that civilians never discover evidence of the war between the Lycans (werewolves) and the Death Dealers (vampires). Wiseman explains, "The cleaners, we haven't seen in the first film. The cleaners are a new addition to this, in which we find out who they're working for, what exactly they do. But that's exactly what they do: They clean in some fashion of the sense, like a cleaning crew,"
