The vampire-werewolf movie, Underworld, looks like it was shot on leftover sets from The Matrix, not to mention copiously uses the bullet-time special effects The Matrix made popular. Even Kate Beckinsale's outfit cops the Trinity latex bodysuit.
It's interesting to see Beckinsale in a more actiony, less bodicey, role, though, even as the undead. Scott Speedman (oh, Ben Covington) co-stars.
See the Underworld trailer.
