The antagonist in this movie is Simon Gruber (Jeremy Irons), brother of Hans Gruber (Alan Rickman, who, like Irons, was an English actor playing a German). Hans was a German criminal who was killed by NYPD cop John McClane (Bruce Willis) at the climax of Die Hard, the first film in the series. It first appears as though Simon is out to avenge his brother's death, but it is later revealed that other motives are at work.
