What did they spend that reported $62 million on in making "Die Hard 2"? Apparently not on getting the details right. Waiting for his wife's flight to arrive at Washington's Dulles Airport, Bruce Willis in an early scene rushes to a public phone to call her. For several long seconds the camera lingers on Willis and the phone company logo: Pacific Bell--which serves only California. How did the amusing goof happen? Studio chief Joe Roth, "Die Hard 2" producer Joel Silver and director Renny Harlin won't say. "The official word is: nobody wants to talk about it," says a Fox spokesman. Also, would the producers please stop making it appear in ads that the movie is called "Die Harder"? Next time pick one title and stick with it.
