Die Hard 2

In the first Die Hard (1988), John McClane only had a few scripted one-liners. However, Bruce Willis ad-libbed many one-liners, and audiences liked them. So much so that in this sequel (and the next one), more gags were added, and Willis was told he could ad-lib as much as he saw fit.

Airport runways do not have manholes. Additionally, any manhole cover which could be lifted by one person would easily be crushed by a plane.

TV Versions, including that shown on the WB Network, edit out much of the violence and much of the profane dialogue is redubbed. Willis's redubbing is quite obvious because the new voice sounds nothing like Willis. Despite the overt dubbing of Willis's dialogue by a sound-alike actor (who really doesn't sound like Willis, for that matter), this version also utilizes dialogue from other characters to replace John McClane's. As John is leaving the elevator through the roof, he tells Samantha to "Fuck off." In this TV version, the word "fuck" is dubbed over with William Sadler saying "joke" from earlier in the film.
