If Movie Franchises Kept Going (and Going, and Going)

This week, Bruce Willis will return as ever-wisecracking, endlessly resourceful and seemingly immortal New York cop John McClane in "A Good Day to Die Hard," the fifth installment in the "Die Hard" franchise that began way back in the summer of 1988.

It's rare for a movie series to last for so many chapters, much less over the course of 25 years. But it does have us wondering what it might be like if some other popular franchises from yesteryear had the sturdy set of legs that John McClane seems to have. Here are a few "What-If?" concoctions that imagine a world where every series is as "Die Hard" as the one with Bruce Willis.
