About.com sprak met acteur Bruce Willis, die vertelde dat er al het een en ander in gang is gezet voor Die Hard 4: Die Hardest.

[eng]Willis said the project is still only in talks, and he's having a hard time accepting a concept that would top the original trilogy. "We're talking about it. We're having a contest to come up with the ending. The problem is... I have no idea, what can we do? Have two planets crash into each other? Juggle an asteroid maybe?"[/eng]
