I put this news up a few days ago and then it was only speculation but i am reading that Kate Beckinsale is genuinely in line for a brand new Underworld trilogy. Nothing is confirmed but i read that the lovely Kate is disappointed with how things are working out right now (she had several great films buried due to financial concerns and studio delays.
Getting back into the Underworld movies might be a good move if they get the films to be great but it would have to be just that as Kate herself said she feels that she needed to move on from them.
Instead of a fourth film the producers are aiming at a new trilogy and it would be sold as such, which would be a much smarter marketing move and what with 6 proposed spiderman movies and a possible 6 Terminator films and even Saw 6 out at Halloween its not impossible that we'll see Underworld 6 sometime in the next few years.
And let's face it, who in their right mind wouldn't want to see the gorgeous Kate back in latex as Selene?
