Directed by: Len Wiseman

Visible crew/equipment: Just as McClane jumps down the cab of the semi, there is a quick shot where the camera shadow is visible on the semi. (01:43:05)
Visible crew/equipment: In the scene where John and Matt are in the middle of an alley, with Matt using the mobile to locate the power hub, the crew can be seen from the reflection from the glass behind Matt.
Plot hole: Since they took down the telephone network, it would have been impossible for Justin Long to even be speaking to the emergency response woman for the car, much less send a signal to start the car up.
Suggested correction: Is it possible this is a satellite phone call akin to Onstar?
No, the BMW system requires a cell signal to work, which was taken down earlier in the movie.
Matt Farrell: You just killed a helicopter with a car!
John McClane: I was out of bullets.
Trivia: Bonnie Bedelia makes a cameo as John's ex-wife, Holly, via a picture of her driver's license. To illustrate the divorce, Holly even uses her maiden name, Gennero. (00:36:55)
Question: Is the "Fire Sale" procedure used in this movie a real-world idea or just a movie creation? Could it ever happen?
Answer: It is strictly hypothetical and most likely couldn't happen without having many, many insiders and the best hackers in the world, but even then, who knows if that could be probable in a "Post 9/11" climate.
