Fox has finally gotten around to confirming the rumor we brought you months ago, and now Justin Long is officially on board as part of the cast for the fourth Die Hard movie, Live Free or Die Hard.

Justin, permanently typecast as a computer, will predictably play a computer hacker who helps Bruce Willis's John McClane beat up on a terrorist organization.

Variety says that in addition to Long, actress Maggie Q will join the film. You might remember her as the leggy female member of Ethan Hunt's spy team in Mission: Impossible 3.

Live Free or Die Hard is expected in theaters next fourth of July, and it's being directed by Underworld helmer and Kate Beckinsale hubby Len Wiseman.
