What went down: "Underworld," indeed. Playing a leather-bound vampire soldier, actress Kate Beckinsale went into the filming of the vampires vs. werewolves saga with longtime boyfriend, fellow Brit Michael Sheen (the David Frost of "Frost/Nixon"), as her costar. Maybe it was Len Wiseman's excellent direction of the movie, but Beckinsale broke it off with Sheen, with whom she had a daughter, during the movie production and soon after began a relationship with Wiseman. The two married a year later. Beckinsale recently signed on to "Underworld 4."
